I can successfully add a custom domain on external container app environments. But when I try the same on an app in an internal container app environment, the validation process just hangs (More than 12 hours now). I have confirmed that the requisite DNS records have been added correctly. This is where it gets stuck:

The docs state that if you are using a free managed cert, then your container app environment has to be publicly accessible. I’m bringing my own cert which does not seem to have any such requirement.

Is it possible to add a custom domain to an internal Azure Container App environment?
