Hi Andrew Straw, I want to help you with this question.
As I understand your question you need to know if your configured Edgio Service already migrated to Frontdoor automatically, right?
I saw such behaviours at customer sites, I looks like Microsoft did some things in the background to hold the systems running.
We see no longer Edgio services in the resource only Frontdoor and Endpoints (I assume a combination of Azure CDN classic, also not the best for the future - deprecated in 27)
However, please follow the steps here and double check if everything is already done from steps:

To verify it, I would open a Support Case, when its a high critical service.
