Up to yesterday, my PT Tournaments list would update whenever I joined a tournament. Now, it's staying static and hasn't displayed anything since it froze. I'm playing on V21.3.45 (the most recent patch) and regular PT works, so I have no idea what it could be. Imgur link below shows start screen and 'show all tournaments' (I'm in three right now).
