Operation could not be completed ERROR

Apple music will sometimes Show an Error, Operation could not be completed (-42670). These are downloaded songs. Not even trying to stream via Icloud.

I am also still having problems with Audio devices switching on its own.

I've tried resetting my phone. redownloading everything. all 60gb of it.

Multiple restarts.

Nothing works. Hope apple can see this and look into it, and maybe 14.7 will fix these problems. If only You could downgrade.
