Bank Not Supported
We have close to 12,000 connections to both large and small financial institutions across the country, and it's possible that some of the smaller credit unions are sometimes unsupported.
When you attempt to link your checking account you need to pass the security steps that are set up for the account. If you cannot do this successfully (i.e. answer security questions or complete a 2FA request), you won't be able to link your account.
If you do not have a sufficient balance in your account to cover the purchase, you will not be able to finish the transaction with Stronghold.
