I changed to a FQDN to deploy jitsi meet.
Now on Debian10 rooms (and /some/ settings) are still present even after purge purge reinstall. After reinstalling, it seems to remember the settings made for jitsi (and re room in particular), even after re-installing. I even saw the config dialogue/wizard.
Also: it remembers the names of previously used rooms.
How can I change this and start with a blank slate?
Where are the settings located on my file system?
