My connection to BMO Mastercard broke a few days ago and it won't reconnect. The BMO site states that something went wrong and to try again in a few hours. It continues to fail. It appears that the site has undergone a redesign. Is this something that the QBO developers are aware of?
Open your QBO account on any private/incognito browser. If the same error persists, you can use MT Online or one of the converter tools (e.g csv2qbo @ $60 one time license) for the time being.
You have clicked a link to a site outside of the QuickBooks or ProFile Communities. By clicking "Continue", you will leave the community and be taken to that site instead.
