Hello. I’m having the same problem. For a bit more than two days now, I haven’t been able to play a track without problems. Most of my library is in ALAC, so I made a test uploading some FLACs but it has de exact same problem. So basically, I’m not able to play any track using your service. I’ve tried with albums I uploaded just a couple of days ago, and albums I uploaded years ago. Strangely, some tracks load almost instantly, while I get just a couple of seconds of most others, before the playback starts stuttering.
Fixing this problem will be much appreciated as with the quarantine, music is one of the things that keeps me sane.
