Since a few weeks, my Dropbox app is always updating thousands of files, whenever my computer is started, taken out of sleep or hibernation. I think it started after I used Dropbox to briefly store a lot of small files on a secondary laptop. Searching on the internet, I have found more people with similar problems and I have tried some of the suggested solutions, but so far to no avail. This is on Windows 11, Dropbox plus subscription with selective sync enabled (my whole dropbox doesn't fit on the laptop).
What I have done: remove and reinstall Dropbox; remove, delete dropbox cache folder, reboot laptop, reinstall Dropbox. At first the reinstall seemed to work but it didn't solve it permanently. Any other suggestions?
