What’s New in tvOS 13.3
Apple’s new tvOS 13.3 update is similarly minor, but adds one small change that will likely make a lot of Apple TV users happy.
Users are now able to switch the main banner interface in the TV app from What to Watch to Up Next. That means you’ll see the shows and movies that you’re currently watching instead of curated or algorithm-generated suggestions.
That option can be accessed in Settings > Apps > TV > Home Screen. Just change the Top Shelf section to Up Next.
Besides that, it isn’t clear what changes tvOS 13.3 makes to the Apple TV operating system. Apple’s release documentation says it includes “general performance and stability improvements.”
