"This Apple ID has not yet been used with the App Store" error and I can't log into the App Store

Hi, I'm trying to log into the App Store on both my MacBook Pro and iPad and every time I attempt to on both devices, I receive a notification telling me that "This Apple ID has not yet been used with the App Store" with two options given to either "Cancel" or "Review"

Obviously selecting "Cancel" does nothing. When I select "Review", on my MacBook Pro I'm always lead to an error that says "We've run into a problem. Please try again later." On my iPad, selecting "Review" causes a page to appear which is forever stuck loading.

This error has been persisting since yesterday when I first tried to log in and basically I can't log in with my account on the App Store on both devices because of this.
