There’s something funny going on with Wallet and Apple Pay on the latest beta. I’ve just received an email from Amex saying that my card has been successfully removed from Wallet on my iPad, but I haven’t touched the Wallet or Apple Pay settings.
If I go into my Apple ID settings on my iPhone or iPad then try and go into Payment and Shipping, I just get an endless loop of “cannot connect” then being asked to enter my iCloud password.
