Hello there, userjwaterburyelectr.
I understand how challenging this situation can be, and I’m here to help you resolve it.
First, may I confirm if your new credit card is under BMO? If yes, please take note that QuickBooks Online (QBO) doesn’t allow you connect both a parent account and its subaccounts. If the credit card transactions are downloading into the parent account, you’ll only need to connect the parent account. If you try to link both, you’ll get a message that the account is already connected.
For more information about setting up parent and subaccounts, you can visit this article: Set up the parent and subaccounts.
If your new credit card is a separate account, the first thing to do is confirm that it’s active and visible online. Log directly into your BMO online banking account and check if the credit card appears on your account summary page. Also, ensure the new card has no restrictions that might prevent it from sharing or syncing data with third-party apps like QBO.
Once you’ve confirmed the account is active, I recommend using the actual URL of the BMO website when trying to link the credit card to QuickBooks Online.
If you have any other questions, feel free to let me know. We're here to assist you.
