PIX transfers follow the rules of the Central Bank, which set a monthly limit on transfer attempts.
This limit is not related to the transfer amount, but to the number of attempts made. Once the limit is reached, you will need to wait until the following month to use PIX again normally.
What to do if this happens:
If you receive an error message when trying to send a PIX, take a screenshot.
Send us that screenshot so we can review your case.
In some cases, it is possible to reactivate PIX transfers without waiting until the next month.
