If you are using a service that suddenly stops working or appears unusual, this is likely the reason. You don't need to repeat the question.
The developers are already working on the issue and will gradually restore the service. Thank you for your patience.

Affected services: Spotify, Amazon Music, Apple Music, TIDAL, Audible
