I've had an issue starting 6/11/24 where my Quickbooks Checking account won't update with error code 9999. I've tried a private browsing window with the same result. There is no way to disconnect and reconnect a QB Checking account, so there's no option there. Anyone else having this issue?

As these are both Intuit products I'd expect it to work more reliably than an external bank.
