Cannot Redeem 3 Months Free Apple Arcade
I just bought a MacBook Pro and got an email that I get 3 free months of Apple Arcade. I went to the App Store and clicked on arcade and clicked on the 3 month free tab. I input my Apple ID and password and it thinks for a minute and then comes back with a screen that says I have to sign in with my Apple ID and has a "cancel" or a "buy" option on the bottom of that screen. Why?
