That happened to me too. Only it was $19.99! Come to find out it was an App I had purchased not too long ago that took it's time going through. Somehow, signing up for the Apple TV+ triggers something and it looks like they are charging you for it but in reality it's for another item. Weird.Mine said my new iPhone gave me a free year, and I clicked to start... it asked me to double click to confirm... and then it immediately billed my Apple Card $5.41. Is this supposed to be a temporary authorization?
