Hi there, @LKHforWZ. 

Thanks for taking the time to share your concerns here in the QuickBooks Community. 

At this time, the investigation is still open. Our engineering team expects to resolve this matter as quickly as possible. For now, there are a few different workarounds shared so you can send your invoices while waiting for a resolution to be posted by our engineers. 

The workarounds shared: 

• Save your form as a PDF and send it via email through your business or other email address.
• (For invoices or estimates) Send your customer a link to their invoice or estimate through SMS or messenger service. Simply select Save and Share Link, then Copy Link and paste it into your SMS or messenger service.
• If you have a Gmail or G-suite email account, you can use the Send with Gmail feature to send QBO forms from your address: https://quickbooks.intuit.com/learn-support/en-us/help-article/invoicing/use-gmail-address-send-invo...
• Save your document as a PDF, print it, and send your customer their form via mail.

You'll want to ensure your open case number is attached to the investigation. This way, you'll receive email updates and will be notified once this matter has been resolved. I recommend contacting our Customer Support Team to ensure your case number has been connected to the investigation. You can use the steps by my colleague, Liera, above to connect with an agent directly.

Please let me know if you have any questions or concerns. I'm always around to lend a hand. Take care!
