At least mine got fixed by signing out and signing back in. But I also only had 1 file sync issue. And I don’t exactly remember if I had to add the file back in or not but since it was only one file, I didn’t mind too much. But I can imagine if you have annotated a bunch or a lot of files were out of sync then it can be a huge pain.
Hi - I’m running into the sync issue as well. I’m trying to use an older iPad Pro (iPad Pro 10.5", I think from 2017) for reading/annotation, but it does have iPadOS 17.6.1 and I deleted/reinstalled the app from the app store.
Interesting - resolved now
