apple watch won't play any music
The watch can't play stations, can't play songs in my libraries, except for those already downloaded (no "cloud" to the right of the song). For stations, it just shows the name of the station, as if it were still trying to load the music, then it automatically pauses. I unpause it, it pauses again. For the not downloaded songs, the song name is shown, the song seems to be playing (the button says so), except that it isn't. It has been working fine several days ago. I tried restarting both devices (watch and iPhone), but no effect.
Help me out here, it's getting extremely frustrating.
