Hi,
When I try to login to the tittle (5F860), getting the error "This request is not allowed due to API usage limits for the title". I contact playfab team may times and got the response that the account was blocked due to non payment of dues of $8.0. So I payed the amount on 29th Novembers and getting response as the account will be reopened with in hours.
After waiting 72 hours getting the same error.
