Endless loop for login to AppleTV+
"Before you can sign in on the web, first sign in to the Apple TV app on your iPhone or iPad. On a computer, sign in to Apple TV or iTunes."
I have a valid AppleID. I go to Login to AppleTV+ I put in my AppleID and PW, A box opens: "Before you can sign in on the web, first sign in to the Apple TV app on your iPhone or iPad. On a computer, sign in to Apple TV or iTunes." OK. Repeat. Also happens to Itunes. Happens on PC, Roku too. Happens on Firefox and chrome. I just want to give them money and sign up for Appletv+ why don't they want my business?
