It can get cumbersome looking for apps to download for your Apple TV. Thankfully, Apple has decided to introduce its Categories section to the tvOS App Store. There are currently only two categories: Games and Entertainment. But those two seem to be central to the Apple TV experience anyway. Fourth-generation Apple TV owners will be able to find the Categories section at the top navigation bar of the App Store. If it isn’t there, force quit the App Store in the tvOS app switcher and then reopen.
