Your account might have been blocked due to compliance reasons. If this is the case, your card was also blocked in the process. Some reasons for this might be that the tax information you have entered is incorrect or that you have a garnishment.
Did you unfreeze your card and it got blocked again after making another transaction? The most common reason why it got blocked again is because the PIN was wrong. Please try to change your PIN and make sure your card is unblocked in the app before trying again. Also, make sure to confirm the transaction with the push notification. If you don’t confirm it, the card will be blocked for your security.
