Access returns right away. As soon as the payment is confirmed, the system reactivates your account automatically and the block disappears, with nothing else for you to do. Usually you just need to reload the page. You don't need to open a ticket or wait for manual approval: confirmation of payment, by card or Pix (Brazil's instant payment method), triggers reactivation. Note that paying an overdue invoice does not change your original due date, which stays the same for the cycle.
