I know the importance of sending invoices to your clients, Counttuts.
I have looked into our records and found that other users have reported the same issue when sending invoices. Right now, our product engineers are investigating the root cause and working on a fix. In the meantime, I'd suggest contacting our Customer Care Team. They can add you to our notification list and provide updates on the progress of the investigation.
To reach them, click the ? Help button at the top-right corner and select Contact Us to talk with a live agent. Ensure to review their support hours to know when agents are available.
For future reference, you can find detailed guidance on receiving invoice payments in this article: Record invoice payments in QuickBooks Online.
