Hello again, Synergy21. I appreciate you keeping us updated and providing a screenshot.
I understand you've been through a lot to resolve this issue as soon as possible. Since you're still unable to reconnect Bank of America account, I recommend getting in touch with our Customer Care Team. They have tools capable of pulling up your account in a secure environment, which we are unable to do so here in the Community for security reasons. It will also provide engineers with the data needed to look for the root cause, so they can apply a permanent fix to the issue.
To contact them, here's how:
- Log in to your QuickBooks Online company.
- Select Help at the top right.
- Select Contact Us to connect with a live agent.
For future reference, visit our website to see our help articles: QuickBooks Online Self-help.
Post again in the Community if you need anything else, I’m always here to help. Have a good one!
