I created a portal website and went through the steps provided by Microsoft to add a custom domain, this is the document https://docs.microsoft.com/en-us/powerapps/maker/portals/admin/add-custom-domain. The problem I have is that every time I type the URL, it keeps redirecting to the .powerappsportals.com which is not what I want. I had asked Microsoft service if the custom URL will be redirected to the .powerappsportals.com and they said no, so that makes me believe that there should not be any redirecting going on. The environment is a production environment. Has anyone encountered this?
