Will an HBO Max subscription/app purchased through Comcast X1 Infinity be included as an app on my Apple TV device? Or concurrently, be included on my Comcast X1Infinty device if purchase thru my Apple TV?

Hi there 4Terry,

Thanks for using Apple Support Communities. It sounds like you have some questions about how your subscriptions work for TV channels. If you subscribe to TV channels directly through Apple you can find those channels in your Apple TV app when signing in to your Apple ID. If you subscribe through your TV carrier or the channel's app itself, you would need to contact them for help accessing and viewing content, but generally it can be found on the TV channel’s app or on your TV carrier’s app.

Learn more about Apple TV channel subscriptions here: Subscribe to Apple TV channels in the Apple TV app.

We hope this helps!
