Why is my groove music not playing music anymore?

[Sengrik Sangma]

After I updated my phone my groove music is not playing any music anymore. What should I do?

Mine is not either, any other music app plays fine though.

I am having a problem with this too. It shows that groove music is playing but no sound is coming out while everything else works fune. I'm hoping they just broke it and need to patch it but no one seems to be talking about this even though it seems like a pretty big problem when a music player app doesn't play music...
