Thanks - I was told that someone from Quickbooks would be in touch when the issue was resolved, so I will wait for that notification and I will update this topic if I hear anything. (I suspect most QBO users don't have the time to initiate a chat, verify all the account/company info, and provide context on the issue to a support representative just to see if there's an update on a known issue, so that's why I shared about it here in a hopefully more visible way.)
