So I just got a notification of a free year of AppleTv+ even though the last thing I bought was an iPhone X almost two years ago. The only thing I can think of is I recently had my phone replaced through AppleCare warranty service. If that was the trigger then I guess they are just sending the offer to any newly activated device id rather than matching actual purchase history? Now that I think about it I suppose that would make sense. If I were to buy six phones and hand then out to friends/family it would make more sense to offer the year to them and would be easier to implement.
