I bought two AppleTV devices on 9.24.22 and set up an AppleTV account the next day. I saw no offer for 3 month free/trial, only the 7 day trial. I want the three month, of course. How can I manage this?! I have not found a way... NO ONE to write to!

The offer is for users that bought a new Apple TV box from Apple or from an Apple Authorized Reseller. The offer is available to new subscribers, users that haven’t had or tried Apple TV+ before, including through Family Sharing. The offer is available for the eligible account that first set up the device. Multiple devices will not bring more offers.
