Purchased iPhone12mini in Nov2020, not able to access free year Apple TV+
Since Nov 2020 purchase of new iPhone12mini through T-Mobile, I have not been able to access the free year of Apple TV+. Each time I try to set up or subscribe, I am asked to pay the monthly $4.99 fee. I have tried most tips & tricks available through Google searches, but no luck. Is this an issue for Apple Support to allow access? I also have the full AppleCare+ as well if that makes any difference.
