Their AppleTV app is super buggy with same bugs for years. Most annoyingly it stars playing same video I already watched a while ago after resuming the device from sleep. It also often zooms-in 4k content after resuming, you have to kill the app to fix it.
It often resumes video at a random location after you paused it, you have to manually rewind it.
Some of these bugs are like boomerang, they come back after a year or so.
From UI perspective, they continue to hide the "recently updated" section, which should list your subscribed content only, and slowly turn it into a TikTok like app, serving you the content they think you need to watch, not the content you subscribed to.
