I've been using premium for over a year now and I never came across this problem before. For some reason, my Spotify cannot play any songs from multiple artists and groups. This problem is happening on my desktop and my mobile app. Even though the songs aren't greyed out, I still can't play the music and it just says the song is not available when it clearly is. This has been going on for over a week now and I've just been waiting for an update to fix this but that never came.
Hopefully everything's working fine now. It's been a while since the last update on the post, so we'll be closing it for now. If you guys still need assistance, feel free to get back to us at any moment.
