Yes, you can remove the new bank account if no transactions have been posted to it yet. Since the new bank feed created a new account in the Chart of Accounts, we’ll need to disconnect both feeds first, then reconnect the new feed to the old bank account.
After that, you can deactivate the new account or merge it with the old one, as long as no transactions were created in the new account.
I’ll keep this thread open in case you have any updates or need anything else.
