New 64 bit droplets are not working in macOS Catalina and Photoshop 20.0.6. When I save a droplet, it's showing an incorrect modification date and time in the Finder of Aug 13, 2019 at 11:56pm. Droplets open but do not complete any actions or give any errors, they just don't run.
Uninstalled and reinstalled photoshop, same issue continues but the modified date is now from today, but still static, doesn't update the time modified correctly. I also tried creating a new action from scratch to make the new droplet from and same issue. ALL droplets appear to still have a 32 bit app inside the package contents/resources folder inside the droplet.
Apparently Fixed in PS 20.0.7 according to the known issues page...
Update to Photoshop 20.0.7 and recreate droplets.
