To be fair, this happens to me also in Debian Gnome, but very very rarely. On Windows, it keeps me from ejecting the drive until after I try it 4-5 times. Every time. In any case, lsof can help identify the culprit.

lsof | grep DRIVENAME should give which program is keeping it.

Same when you try to remove an external drive.

I wish there was a better way to scrobble from Tidal to Listenbrainz on Android. I know that the Listenbrainz app itself can read system notifications and get song info from them. But the fact that you need to give permission to it for all types of notifications is not an easy decision to make.
