Hi cetanorak,

I appreciate you keeping an eye on this investigation. Please know that when you're added to the list of affected users, our Support Team will update you once a resolution has been released for this issue. 

Our engineers treated this particular behavior with the utmost urgency. As a workaround, create the invoice separately from the estimate.

For now, I suggest giving us a quick call to receive updates and provide this escalation number: INV-28978. Then, follow the steps provided by my colleagues to get our contact information.

I'll be sure to update you on this thread once a permanent fix has been implemented. 

Thanks for your patience. Please let me know if there's anything else you need. I'm always here to help.
