Why can I not reconnect my banking?

Hello, @philip-lamb.

Can you tell us more about the bank that you're having trouble with? That'll help us check to see if there's an ongoing issue with it.

For the meantime, you can manually download the transactions from the bank and then upload the file to your account.

Check this article for more information: Manually upload transactions into QuickBooks Online. From here, you can now categorise and then reconcile the transactions.

Let me know if there's anything else that I can help. I'm always here to assist. Take care and have a great rest of the day!
