To re-authorize a bank, tap on the More tab, then tap on "Your Banks". You should then see an exclamation mark next to the bank that needs re-authorizing. Tap into it, and re-enter in your credentials, and you should be good to go. Some banks are more stringent on their security measures than others, and will require you to re-authorize your account more frequently. There is not much we can do in this case, but feel free to contact us at [email protected] to let us know about it. You may also want to contact your bank directly and let them know you\'d like them to improve their support for apps like ours.
