Getting Expo Web To Work with Custom Domain on Github Pages

It took several days to work through the issues so I wanted to put this out here as a help to anyone who has this same issue in the future.

I followed the instructions in the docs to deploy my website to github pages:

However, when I attempted to use a custom domain in the github settings I continued to get a 404 error with issues related to the Manifest.json.

  "homepage": ""

Hopefully, this helps someone in the future.
