I am unable to add my credit card/link account to https://cards.barclaycardus.com What can I do to make this work?

This bank connection issue typically occurs when there is a syncing problem between your bank and Intuit, which can cause bank unavailability or login failures. To provide the right solution, could you let me know if you encounter a specific error message when accessing your credit card account? Sharing a screenshot would also be incredibly helpful.
 

In the meantime, let's troubleshoot by accessing your account via an incognito window to see if this is a browser-related issue. Please also ensure you have a stable internet connection and check your bank's website for any ongoing maintenance or service advisories, as these are often major contributors to syncing disruptions.
 

Please don't hesitate to drop a reply below if you have any other questions or concerns.

Thanks for your reply. I have attached a screenshot. 

I have also tried this on a smartphone via the app and still have the same issue. I have not had the ability to try via a different browser and in an incognito window. 

looking forward to your reply to get this resolved
