"Scrobbling now" on last.fm web page dependent on "Now playing" notification being turned on in the app

[TormodLandet]

If the "Now Playing" notification is turned off in the app the "Scrobbling now" status on the last.fm webpage stops in the middle of the song and that makes "Scrobbling now" visualizers like https://descent.live/ not work as intended (showing "nothing on the air" half the time). When the "Now Playing" notification is turned on in the app this does not happen
