Hey Crushing1523!
We’ve received a few reports of this issue this weekend and have replicated it in the office, it’s likely yet another Spotify API update which means we will be keeping an eye on our Spotify provider to put out an update for which we will then package into an update and ship out
This has happened a few times in the last six-ish months, it seems that the average turnaround thus far has been a week, the longest being two weeks. Nothing to worry about too much at the moment, just keep an eye out for an update to fix this soon.
In the meantime, there’s all sorts of workaround stream types: DLNA, Airplay, Bluetooth, even LMS (pending their own Spotty Spotify plugin having updates available)
