iCloud Photos for Windows has uploaded more than 25K items, but is now stuck on about 7K items for almost 4 weeks.
I tried disabling and re-enabling Photos sync, restarted, deleted the settings of the sync process and re-entered it... nothing helps.
How can I tell what is making it "hang" for so long? I saw a post from 3 years ago (Photos stopped uploading to iCloud. What can I do?) that shows a way to display the file causing the issue - but it's on Mac.
What can I do?
