I've installed Dropbox (Flatpack) and everything is working fine as long as I just let Dropbox use it's default folder or keeps the folder on the system drive. The problem is that I would like to have the Dropbox folder on another drive, which is found under /media. When I enter Dropbox Preferences -> Synchronization -> Directory, Dropbox can't see /media. I've tried to enter the path but it doesn't work.
The disk I want to reach is mounted and is working/accessible for other programs.
What am I missing/doing wrong here?
