Unable to connect to our bank for days now

I'm glad you made it here, user74250.

Let's sort this out by looking into the possible reasons why you're unable to connect you bank in QuickBooks Online (QBO).

To do this, I may need additional information by asking some questions. Did you get an error message? Which bank are you using? Any details can help me identify the exact resolution for this.

In the meantime, we can try manually updating your bank account to refresh its connection with QBO.

Here's how:

1. Go to the Banking tab.
2. Select the bank account and click Update.
3. If prompted, enter your Multi-Factor Authentication (MFA) credentials and select Continue update.
   

I'll be on the look out of your response. If I can be of any assistance, please don't hesitate to leave me a comment below. Have a wonderful day ahead.
