It's gotten better over the past couple of years. Even Disney+ has a lot of issues like some kid shows will play like 10 minutes of end credits after an episode instead of going to the next one. Not sure if that is finally fixed. In general, Netflix is still light-years ahead of the competition.

Paramount+ on iOS was terrible the last time I used it, too. I tend to binge Star Trek on flights, so I like to download a bunch of episodes. Paramount+ had such a terrible experience (at least 10% of the time videos would be downright corrupted), I ended up cancelling my standalone subscription and getting it through Apple TV so I could use the Apple TV app.

The Apple TV app is 100% the only way to cope with Paramount+. Of all the streaming services I use regularly -- Netflix, Hulu, Disney+, Peacock, YouTube -- it's the only one that doesn't work for me more often than not when using the app directly.
