Lightroom Classic 10.0 not syncing

Hi,

Again, Lightroom 10.0 does NOT sync images from the cloud correctly:

  • 48 raws uploaded on an iPad and fully synced, as we can see on iPhone screenshot (same on web, by the way):

In Lightroom Classic:

 
  • The to sync album appears with 0 images
  • According to sync status: it is "synced"
  • In the settings, it sees the 48, appearing as downloading
  • However, NOTHING happens:
    • No images after a full night up
    • No download activity whereas a speed test confirms my network is ok
  • The ONLY way to "force start" the sync activity is to reboot Lightroom Classic: syncing starts right away so this IS a bug!
  • After rebooting, it syncs 23 images then gets stuck again: 23 remaining!
  • [Edit:] Rebooted a couple of times and now it fails to sync totally!
  • Please find here the Wetransfer LrSyncDiagnostic.zip 

I'm trying several things I don't think I'm allowed to share here, but please acknowledge and fix the sync issues with Lightroom!!

Greetings Antoine, 

Following your information here, I've attempted to reproduce what you are seeing.

  • Lightroom Classic 10.0
  • Lightroom Desktop 4.0
  • Lightroom iOS 6.0.2 (phone and tablet)
  • Canon 5D Mark IV  (photographed 48 images in raw)
  1. Open Lightroom Classic and Lightroom Desktop on Win 10 Machine (2003) and Lightroom Mobile on iPhone
  2. Connect camera to iPad
  3. Import directly into Lightroom Mobile bypassing Camera Roll
  4. Allow to sync to Cloud
  5. Verify Images arrive at Lightroom Web
  6. Wait ~ 40 Minutes from first capture: All Images in Cloud
  7. Wait ~ 5 minutes
  8. View Lightroom on all platforms: 48 images synced.

I am unable to reproduce Lightroom Classic's needing to restart to initiate sync from cloud. It started on its own while sitting at idle.

I am also unable to reproduce Lightroom Classic stalling on sync at 23/48 images. On all devices and apps, sync reached 48 images unassisted.

I will share your diagnostic log with the Classic team to see if they can glean where your issue may lie.

Hi @Rikk 

Thanks for trying to reproduce the issue. I can’t give you much more info as this is my workflow and I don’t have access to much more information. I’d be happy to carry out other testes if required. I also tried and reported the issue with “Smit K’s version” but the issue remains. (Feel free to edit this information)

Also I’m on macOS, not sure it matters. I think the diagnostics might also contain useful info, but hurry up as the link might not hold for long.

Lastly, it’s not the first time I’ve reported similar sync bugs and it has NEVER been reliable.

I reran the test this morning with Lightroom Classic on Mac 10.15.7 as the Catalog synced with the Adobe ID and it ran similarly. It took about a minute longer but still functioned as expected. We will see what the engineering team discovers in your log.

Sure! Let me know if there are more tests I can run or actions I can take when it happens again ;)

I heard back from engineering (check your email). They would like to collect some different logs from you for further diagnosis.

I've received the information and forwarded it to engineering.

Response from engineering: 

"There are 48 images at path /Users/antoine/Pictures/Lightroom/__LR Mobile Sync/2020-11-06/ for which binary is missing.


Can you ask the customer to fix this and see what is the state of sync after that."

Hi @Rikk 

This folder (__LR Mobile Sync) is where I ask LR to import images from mobile. My workflow is as follow:

  • (When) I import on mobile, I create an album with date and description: 2020-11-06 - Descrpition
  • That Album shall be imported in the collection group "From LR Mobile" with the same collection name (date - description)
  • The images are imported in the folder __LR Mobile Sync with subfolder formatted by capture date
  • Note: why the folder structure cannot be inherited is a mystery to me. Ah, having a decent workflow remains a pita, but that's off topic...
  • Once all the images are synced (I can easily check their amount, and it often fails...) I can move an rename the "date only" folder to the "date + description" and move that folder somewhere else to keep synced images sorted from unsyced images
  • Note2: because their is STILL NO WAY TO FILTER SYNCED IMAGES ON MOBILE OR WEB, but again, off topic

In this case, that folder contains 49 images and non missing or to be imported:

In the Finder, everything looks fine:

49 images and one .lua file = 50 files

All image are the amount of MB expected

Hope it helps ;-)

I heard back from the engineer: 

"In that case, ask him to unsync and resync this folder. As per LrC, there are few images which it is not able to upload because binary is missing."

I couldn’t try it because the album got synced after a couple of reboots (I’ve sent you a second log, by the way).

I’ve tried again to sync two other series of 40 raws but couldn’t get it to fail, this time...

What does he mean by “binaries” missing? Where? On my drive or on the servers? I haven’t deleted or even moved anything. In that case, he should be able to locate the missing “binary” and fix the bug, right?

And upload? LrC is supposed to download, or am I missing something?

Anyway, unsyncing and resending the collection could be a workaround but not a fix.

in order:

Binaries=raw image files

Missing on your drive not on the servers

No - a bug is not indicated here.

Upload - The diagnostic file indicates you had uploads pending for missing local binaries in addition to the downloads that were occuring.

I've never had to unsync and resend a collection except as a diagnostic step. It is not a part of normal operations nor is it a workaround.  As you appear to be no longer experiencing the issue it is probably not in play. 

At this point, I would run Lightroom normally and at the point you encounter this issue again, create a log immediately and post back here for next steps.

It looks like the engineer responded to you direct via Email.

Thanks Rikk,

Files are obviously mission, as sync cannot be completed. And if it's not a sync issue, then it's an internal file handling issue in classic.

Uploads for missing files ? Does the log tells us where? I could have a look if those images rings a bell. Related to the sync bug or totally different images? I do have a majority of my raws on an external hard drive, but NOT my catalog.

Sure, that was my plan too: I wasn't able to recreate the bug, but I'm sure it will happen again in the future, as it has happened before. The only workaround is to reboot LR. Hasn't that ring a bell at the engineers? Il keep you and the engineer updated with the logs.

I am having the same issue. Did you find a solution?

@Benjamin Ibarra

No, Sync has NEVER been reliable or worked flawlessly. You just cannot trust it, and images on mobile CAN get lost.

If you need a sync solution, use a third party solution such as OneDrive or Dropbox and the watched folder feature.

See sync as a way to upload smart previews from Classic to mobile but not as a reliable tool on mobile to sync with your desktop.

@Rikk , I've haven't been using LR much lately, and today it failed again. I sent the logs to the engineers.

I see them in our inboxes.  Let's see what the engineers say.
