Hello @Gary McGill - Thanks for reaching out to our support and working with them while the support was working on the issue.
Looks like the issue is resolved now and the domain was restored to your subscription. And I also understand that the App service team was unable to restore the original domain karenmcgill.com because it is registered for another registrar as informed by the internal team engaged.
This was by design as we are fully committed to ensure that your issues or concerns are resolved.
You can also use this link to communicate your feedback https://feedback.azure.com as this goes directly to the Engineering team responsible for building Azure.
Hope this helps other customers as well that come across this issues.
