I have an old AppEngine project which is mapped to my domain. I recently transferred this domain to Google Domains.
I created a new AppEngine project which I now want to map to my domain instead of the old project. When I attempt to do so I get the error "my-domain-name is already mapped to a project." That makes sense.
However, when I attempt to delete the mapping from my old project (console.cloud.google.com/appengine/settings/domains?project=my-old-project-name) I get an error: "Error Sorry, there’s a problem. If you entered information, check it and try again. Otherwise, the problem might clear up on its own, so check back later. Tracking Number: xxxxxxx Send feedback "
I've tried this several times so this is for sure not clearing up on its own. (I've also tried sending feedback but not gotten any reply)
Any idea on how I can move the mapping from my old AppEngine project to the new AppEngine project?
