I have previously synced my entire catalog to the lightroom cloud successfully. recently, I set the flag to "unflagged" on all of my images, and now the entire catalog is stuck syncing. There is zero progress for days. I have tried logging out and loggin in, uninstalling and installing... but nothing is working
Thank you Akash. I am having this problem with Lightroom Desktop (version 4.2) not Lightroom Classic. I also use Lightroom Classic on another device, but this problem is a problem in non-Classic Lightroom. See attached screenshot.
