Stuck in a Review Account loop
Solution which worked for me:
- Open Music app
- Sign-in with Apple ID
- Accept agreement which would not initiate in appstore.
- Open AppStore & sign in with same Apple ID.
It may be late but could be useful for someone else.
So, I just faced the same issue where I was being asked to Review the iTunes account in a loop.
The solution is to open your AppStore > click on your Profile Icon from the top right corner > and complete the review process there.
