'This Apple ID has not yet been used with the App Store' error
Solution 1:
The resolution for me was to launch iTunes on my Mac (Music app on Big Sur and later), and sign in from the account menu there.
Have some patience and keep trying if it at first does nothing; I had to log in twice as clicking on the "Review" button on the first attempt did nothing.
I had to accept the terms of service and reenter my payment details, even though I had already done both these things from signing in to the Apple ID website.
In the final step of the log in wizard, I received an error message, but it appeared that nevertheless iTunes was logged in. I could then exit iTunes and launch the App Store, and I was prompted three times to log in, but I no longer received the error message instructing me to review my account information.
It seems that the third time was a charm, because it then displayed a welcome message. When you are signing up on a big day for server traffic, check the store status for outages as well: https://www.apple.com/support/systemstatus/
(Cue here the obligatory grumble about this being an atrocious experience.)
Solution 2:
I faced same problem (the infinite loop) when trying to download app from App Store on my iPhone XS (iOS 14.6). I guess there's a bug to continue the process on mobile.
So I decided to try it on my Macbook and it worked!
My solution is to open TV app on mac then follow the process below:
- Open TV app on Mac
- Click Sign In menu
- You'll get same error like on mobile. Click Review.
- Fill your apple ID
- Continue the process until finish.
Solution 3:
If you've just created a new Apple ID, and it is giving you the message "This Apple ID has not yet been used with the App Store", it is because :
- The payment details are not added, please check that you have entered a valid credit/ debit card in the payment section in the below mentioned link, then try.
- After entering the payment details then sign out from your device and then try again to login, try until you get the welcome page.
Login to appleid, go to "Payment & Shipping" and set your address for both Billing and Shipping and enter the details. I think this helps to get out of that cycle.
Solution 4:
Did you receive a verification email at the email address you set up as your AppleID? If not, log into https://appleid.apple.com using the email and the password you created. In there, you should have options on the screen to verify the email address if it is not already verified.
