[ALERT]: Your Dropbox folder is on a file system that is no longer supported.

[patch91484]

I am running Docker Desktop on Windows 10 and get the message:
[ALERT]: Your Dropbox folder is on a file system that is no longer supported.

This occurs right after linking my dropbox account. It appears the account is linked successfully.
I am not trying to mount any local directory's to container volumes.
I'm guessing this is something specific to Windows 10 and Docker but I'm not sure what it could be.

I've reinstalled my QNAP NAS and I'm getting the same error:

This doesn't make sense, as the volume is mounted on an ext4 fs (/share/CACHEDEV3_DATA):

I am also getting this error on a Linux with ext4 ....
What to do ...?

[longieirl]

Any idea how to work around this?
