Anyone had any issues connecting there bank account? I’m with Barclays and the 3 months ended so it needed to be re added, but it says the account already exists

Hello and welcome to the Community, @bjsterlinglandsc.

We are currently aware of this issue and I've got just the information to help you continue accessing your bank information.

The Barclays have performed some changes to their Open Banking security profile. As a result, all customers will lose 90-day consent for their Barclays Open Banking connection in QuickBooks Online. To get this fixed, you'll just need to complete the re-authentication flow to grant access. Just click the banner that's visible on your Banking page. 

That should do it. If you encounter other banking connection issues in the future, you can check this helpful reference: Open Banking Connection Errors.

Thanks for coming to the Community, I look forward to hearing from you again if you need anything else. Enjoy the rest of your weekend.
