Lightroom CC for mobile: White Balance bug with v4.1 update for IOS (Ipad Pro)

After upgrading to the latest Lightroom CC v4.1 on my Ipad Pro, I'm experiencing a bug occasionally where the white balance runs after adjustment. This problem occurs quite often when I review a recently edited picture again after a while. Moving the white balance slider fixes it temporarily but the problem randomly reoccurs. I did not experience it with the previous version.

Hi, 

could you give some more info on what kind of images run into this issue?
Which iPad Pro are you using btw?

Do you use any other clients besides the iOS version for editing?

Thanks,
Ignacio

Hi Ignacio,

I’m editing it on the latest 12.9” IPad Pro 2018. I’m not noticing it on the desktop though. I’ve uploaded a sample video in the following link

Just to add too that it seems that the WB in the Ipad Pro often needs higher values to achieve the same degree of warmth than LR CC desktop. This happens to those photos that are affected by the bug and often i will overcompensate them in the Ipad and only to find out that it's overly warm after export or viewing from LR desktop.

How are you calibrating your desktop monitor? iPad Pro's are usually fairly neutral, which makes me think your desktop monitor might be a little warm.

Hi, my desktop is calibrated with 1Display Pro. This bug occurs only on certain images and not the entire set. For those photos that are unaffected by this issue, the colors between the Ipad and  desktop are very close, though Ipad tends to be slightly on the blueish side (~6800K) instead of my calibrated 6500K screen. 

The video example I've uploaded showed a vast difference in temp. It is as though there is some syncing error on the adjustment sliders value and is messing up the preview. When I touch the slider, it reverts back to supposedly the correct value that i see in the desktop.

Do you only have this issue with certain images with certain profiles, e.g. RNI Pro 400H? Or do you also see it with other images?

Just tested it and it’s the same if I use the the Adobe profiles (Adobe Color). Preview shows a warmer temperature, touching the slider reverts to the cooler colors. It somewhat seems that the white balance slider on the iPad for these affected images are not reflecting the correct values. I will have to increase the temp to relatively high values to bring in the warmth effect (from experience these numbers are too high but i’m judging based on the image not values). After moving on to the next few pictures and when I check the earlier edited image, the preview has updated with a very warm image (I suppose this was the actual ‘warmth’ with the high values set earlier). Touching the slider revert it backs to cooler image. The WB on these images when viewed from LR desktop are off. I’ve been needing to go back to the desktop to check very image if I’ve overcompensated this from the IPad and it has been a pain. In another post, someone else mentioned a similar issue where the WB edits from IOS and LR CC desktop differs. The common factor I notice that we were both using the Canon EOS R where these problems seem to appear.

Also just to add another WB related issue I’ve encountered yesterday. I’ve exported ~1000 photos yesterday from LR desktop after painfully checking for the overcompensation. During the batch export, some random photos seem to export with the preview instead of the adjusted settings. If I manually export these individually, I can see that the preview will be updated (usually a fraction of a sec) and it is fine. If seems like a sync-timing issue where the batch are exporting it before downloading the edits? This issue only occurs on random pictures and I only notice it with the latest LR desktop v2.1.

Hi Adobe team,

After further experimentation, it seems that the issue lies with the smart preview. If I edit on the original instead of smart preview then the white balance is updated correctly to the cloud and also read correctly with LR Desktop (cross-checked with LR Web). This has been the only work-around. Any update on your investigation and potentially a quick update instead of the normal 2 months wait for the next release? This is a crippling bug :(
