Sync-Problem: Linux Mint 21.3 and Dropbox v194.3.6224

Hi, I have a silly problem.

If I change a small file on my Linux machine, the dropbox-icon will get blue and will show "Syncing" for multiple days.

After a really long time it is going grey again.

What makes me wondering is, that if I go into nemo and look for the sync-status-icons, really everything is green.

And, also the changes can be seen on other devices. (so the file was synced)

 

I already checked, that I am not syncing any hard/soft-links and  that I do not have any strange characters in the filenames. I rebooted several time and already unlinked/linked the whole Notebook.
CPU < 5%

• Memory 90 % free
• No other applications running
• Internet is perfect

Nothing helps.

I also started a script to check the status of all files (dropbox filestatus xxx) recursively and also there I could not see any not-synced files.

Does someone have an idea, what is going wrong here?
Makes it sense to try a Beta version?

Greetings
Juergen
