So I struggled to delete a free Apple TV+ account for a day now (tried different browsers etc) and decided to search if anyone else has had the same problem. Turns out this issue is at least a year old, is known by apple and the Apple support suggests to find someone else with an Apple device to help you out.
Just wow. This can’t be legal by EU law.
Canceling the trial should be possible without an Apple device.
But deleting the account… I bet Apple refuses to do that for you over the phone due to possible social engineering issues. But that’s just a suspicion.
Correct, canceling the trial worked on the Apple TV page, but deleting the account does not work (see my other comment that describes the whole process).
