Thank you for joining in on the thread, vivia.
I see that you've been through a lot of steps to resolve your issue with connecting your Capital One account. I'd also share the same sentiment if this happens to me.
It's hard to conclude that QuickBooks Desktop is having an issue with Capital One bank. Yes, we may have clients who reported certain issues, but this doesn't mean everyone has the same concern. The issue could only be due to a specific error, only happening to a specific bank account type, happening in a certain region, an effect of the changes in the bank's server, etc.
If you've been contacting our Support team about a specific issue (error message, code, or incident), I assume they've already created a ticket so our engineers can investigate that issue further. That's what we normally do when the front-line agents cannot resolve an issue after trying all the necessary steps in our references. If they haven't mentioned about that, you'll want to contact them again or you can post the issue here so I can check it for you.
I'm just right here if you have other concerns.
