Released on July 29, iOS 17.6 introduced a new Catch Up feature for sports viewers in the Apple TV app. With this feature, viewers can watch a series of highlight clips of what has already happened during the game.
iOS 17.6.1 was released on August 7 with bug fixes and security patches. Most notably, the update addresses an issue that prevents enabling or disabling Advanced Data Protection.
Apple says that the Advanced Data Protection bug in iOS 17.6 affected a small number of users. If a user attempted to turn Advanced Data Protection on and it failed, they were presented with a clear error message so they were aware the change failed.
