Welcome to the Community space, @saspin74.
I can provide some insights on how to reconnect your bank.
You'll want to log out and log in back to your QuickBooks Self-Employed (QBSE) Mobile App to refresh the connection.
If the issue persists, I recommend reinstalling the app. This will delete the data and installs new updates. You can also access your account on a regular browser for a better view.
Once everything is all in place, you'll want to check this link for guidance: Categorise transactions in QuickBooks Self-Employed. This ensures you'll be able to assign your transactions to the correct account.
Keep me posted if you have any other concerns or questions reconnecting your bank. I'll be around ready to help you. Stay safe!
