P: Mobile: Error T20200121

Mine doesn’t even fix itself if I edit the photo in my desktop again. It’s so frustrating. I’m spending time to edit these photos and then they won’t even upload properly to Lightroom mobile. Please fix this!

Yes, the problem is still there after upgrading to today's version. The only way to fix the problem is to edit the photo on the Web. It then propagates to iOS again. Could you please fix this problem once and for all? And make it, you know, like a priority? It's juts do damned annoying.

This is a possible solution for error code T20200121.  If you have Virus software installed on your mobile device and if the software includes a "safe browsing" feature or VPN service, this service will interfere with Adobe mobile apps.  I use McAfee and had to turn off this service in order to use Lightroom mobile.  Here is more information.

for me personally I had to go through 3 photos in a stack on desktop, make sure they were no longer in edit mode, then wait for the cloud icon on the top right to finish. then when opening on mobile it seemed to fix it. good luck!

Ugh, it didn’t work for me. Glad some people are finding fixes though!

that worked! thanks Ash

still getting the issue even after force closing and reopening. this is on v 5.2.5

I have figured out that I only get the error on photos that I have "duplicated" on Lightroom on my desktop. I typically duplicate photos I want to edit so that I have an Instagram 1x1 version and then a printable 5x7 version. The only work around I've found is that I have to to save the duplicated photos to my desktop, import them into my Apple photo library, then from Lightroom mobile I have to upload them from my Apple library, add my watermark, then save them back to my Apple photo library. This is extremely annoying and time consuming.

I had this error but it was resolved after I signed out of Lightroom on all devices - 2x iPhones, 1 laptop and 1x iPad. I think 1 device was stuck in 'edit' mode on the image, which wouldn't let me edit the image on another device. Hope this works for everyone!
