I do sync LR mobile with multiple device (iPhone, iPad, android device etc) and desktop in Mac. The desktop's sync status keeps "Syncing 2 photos" for over a month.
I have experience that some photos are stuck in mobile device for partially sync due to network connection broken. In previous cases, i removed the incompletely sync file from the web, or left the mobile device sync everything again when connection is back. Then it could be synced back to normal. This time, I cannot find any incomplete file from the Web version (was having a cross in a grey photo for broken file), and I tried to re-sync everything from my mobile device. However, the "syncing 2 photo" are still there. Any clues that I can figure out what it is sync thus I can do corrective action?
Could you please send me a LR Desktop diagnostig log - best as a private message with a downloadable dropbox link.
You can trigger the log via LR Desktop preferences -> Lightroom Mobile and when you hold down the alt key you will notice a generate diagnostic log button.
