I’m trying really, really, really hard to not go back to streaming piracy, you know. :(

Canceling the trial worked but not deleting the account. You can read in my other comment what the whole messy process looks like.

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).

I subscribed Apple Tv+ (free 7 day trial). I just needed to provide my personal data, email address and PayPal data. When I decided to cancel I could cancel the subscription on the Apple TV+ page, but when I wanted to delete the apple account in itself, I was forwarded to accounts.apple.com where I was asked to login first. When I tried this, I needed to enter my 2FA that I got by email and then I had to enter my mobile phone number for another 2FA. After that the screen that you can see in the reddit post comes up and I cannot proceed past it. I tried this process dozens of times with different browsers and configurations to no avail.

… I now sent in a GDPR account deletion request.

Me too, I tried just a few. On pc #antifascist , #fascist and #democracy didn’t work. On a mobile phone from my colleague #democracy worked though.
