Good to have you joined this thread, Jon.

I appreciate you for sharing the details you've done in fixing the issue

Were you able to perform the steps shared by colleague DivinaMercy_N above in updating your bank? If not yet, I suggest performing them to get around the issue.

If you still have that issue, the last step we'd suggest would be completely disconnecting and reconnecting the connection, to do that go to the chart of accounts page>click on the dropdown next to account history>edit>put a tick in the disconnect account on save box and then save as. Go back to the banking page and add the account, making sure to use the search function to type in the bank to make sure you get the correct connection. When you connecting it should allow you to select the date you want to pull bank transactions from.

You do have the option to manually upload transactions by uploading an excel CSV of   transactions more information can be found in the highlighted article. When everything is all set, you can categorise and reconcile your accounts whenever you're ready.

I'll be around if you have other follow-up questions about your transactions and bank accounts. Simply add them in your reply and I'll take care of them for you. Have a good one and keep safe!
