Got rid of premium because I didn't use it and I don't mind ads. Just went to watch Jujutsu Kaisen after watching some this morning, app didn't bother to remember my position. I finally found my position but had to sit through the same two ads repeated 5 times a piece... After a further minute of watching it's managed to crash over Chromecast... I just wanted to watch the last 10 minutes of the episode but it's taken 20 minutes to get to this point. Setting up a pihole tomorrow.
