It is Nov 23 2020 and this issue still persists. This is ongoing for the better part of a year.  While invoices email just fine but the Scheduled Reports don't, why don't' they just adjust code to be such that the scheduled reports send using the same mechanisms as the manual invoicing emails do?  

I do appreciate the QB team members posting the manual workarounds, thank you for that . 

@aiannarelli :  Thanks for that suggestion.  I had once heard of something called AutoIT that I think was similar, but perhaps your setup is the route to take here :)
