As for the workaround, yes! The estimate will track the partial custom payments.

As for the ongoing issue, our Product Engineers are still working to fix the issue as soon as possible. I highly suggest contacting our Phone Support team if you haven't yet so they can add you to our notification list.

Check out this article for the detailed steps on how to reach them: Contact the QuickBooks Online Customer Support team.
