Summary of the issue you are facing:
Since almost one week the android app doesn’t want to sync. I got “unknown error”.
The files are read and detected and I checked the different app permissions on android : photos, videos and all file access.
I tryied to uninstall and reinstall the app, logout and logon, this doesn’t change anything.
Steps to replicate it (hint: details matter!):
-
Have a folder synced
