Glad to help, @WWMarket.

After doing some research on your issue, I do see some reported issues within QuickBooks Online. It's likely that the root cause of that issue is also what is causing issues within your QuickBooks Desktop for Mac version. Our Engineering Team is currently working with Flagstar Bank to resolve these issues as soon as possible. I recommend letting our Customer Support Team add you to the list of affected users so that you can receive email updates on when the issue will be resolved.
