The only issue I was having is within the music app the album art was correct when the app is open. But when you go to the lock screen it is a different song displaying. It wasn’t even showing the time of the song progress. I eventually just rebooted the phone and it seems to have sorted it for now.
Best advice I can give is report bugs to apple and accept any software updates. Make sure your phone has at least 50% battery life, higher or simply plug it to mains before updates.
Aside from that I think you may need to do a reset through iTunes. Just make sure you back up your data.
