Invalid package family name after getting new signing cert

I’m submitting an updated MSIX package for our app, but I’m encountering validation errors related to the package identity. I have a new code signing cert and cannot figure out how to get the app upgraded with the new MSIX. The Package Family Name has a new hash suffix that does not match the old one. Can MS change this in a support ticket, or is there an easier way?
