#16 successfully built and deployed the app to the gh-pages branch and was visible at https://opencdms.github.io/opencdms-app
However, when I set up a custom domain (and GitHub automatically committed a CNAME file to the gh-pages branch), https://opencdms.github.io/opencdms-app correctly redirects to https://demo.opencdms.org but a blank page is shown.
The image below shows that the JS and CSS files are no longer found (although the favicon is being displayed in the browser tabs)

Removing the CNAME file, the app correctly loads from https://opencdms.github.io/opencdms-app again.

The fix for this issue should include adding the CNAME file containing demo.opencdms.org and also add a .nojekyll file (if this is still required by GitHub pages to prevent Jekyll running?)
