Add HBO max

• If you have an Apple TV box of 4th generation or later, then you download the HBO Max app from the on-device App Store.
• If you have an Apple TV box of 3rd generation or earlier, then your device is too old for HBO Max.
• If you have non-Apple device with the Apple TV app, then the Apple TV app can’t help you for this. You can get apps that the device manufacturer provides, without access to apps for Apple TV, as those are for Apple TV box of 4th generation or later. You can’t install apps into other apps.
