Check the Extra App to make sure you have enough Spend Power to cover the transaction with your Extra Card.
Do you have enough funds in your connected bank account?
If the transaction requires a pin number, make sure what you are entering matches what you set up in the Extra App.
If you are buying something online, make sure that your billing address is the same as the one we have on file. This can be flagged as fraud on some websites.
Check if your bank account has been disconnected in the Extra App.
Check the card tab in the app to see if you forgot to un-freeze your card.
If none of the above have solved your problem, please contact Member Concierge.
