Form Email as part of a Google Group

Form Email as part of a Google Group

Not liking the random and unfamiliar email address that was assigned to our form (accountname-123@forms.zohocreator.com), we made the form email address a member of a Google Group (easytoremember@company.com)

This worked a few times but then stopped.
  1. Directly emailing the form works.
  2. Forwarding from a Zoho Mail address (easytoremember@zohomail.com) works.
  3. But emailing through a Google Group does not.
Creator Support is looking at this, but I'm curious if anyone else has tried this and succeeded.

Thanks!
