I have TIDAL. Just five days ago I had a weird issue. I was listening to a track and it stop. A message popped up saying I needed to RE-subscribe.
What???
I checked my account and my payments WERE up to date.
This is what I did to solve the problem.
I shut down everything. TIDAL, Mac Min, Monitor
I then cleared my browser on my iPad
I deleted the TIDAL APP
I Turned my iPad off
I use AIRSERVER to stream from Mac mini I just shut it down
After waiting about ten minutes I started up everything re-applying the TIDAL app and signing back in using my same password.
HOPE THIS HELPS!
