@hjertnes My wife was trying to buy AppleCare for her newly bought iPad Pro. She needed to get help over the phone because the machine was showing vague error messages with no practical route for solving the problem. Whilst she was talking to the support person, they were able to get it working (this was the good part of it, that support was able to get it working). They eventually were able to get her to the payment screen, where she tried to enter her debit card details.

The form was broken. Like it had a bug. On the iPad... on Safari. She had to use Chrome for the basic form to work.

That's one personal story where as far as I'm concerned the "standards company", which is literally supposed to be the justification for the Apple hype (and premium label), have failed in a big way.
