I just started a trial of Insync to use with Dropbox (on Ubuntu 20.04). Syncing files into a base directory on my main drive works fine.
However, the main reason I’m trying Insync is to work with my external drive - and there I get a “Failed to sync: The filename may be to long…” error, even for as short a filename as “test” (see screenshot).
(Note, re: here, this drive is not encrypted.)
Ideas as to what’s happening here?
