Automatic profile switching doesn't work on iOS

I don't believe that automatic profile switching works in Edge for iOS. When I click a link embedded in an email that points to a web site on my company intranet, Edge opens in the last used profile. If the profile is my personal profile, everything just stops and I am left stuck on an "about:blank" page. 

If I turn on "Ask Every Time" for Automatic Profile Switching, I am correctly prompted to switch to my company profile, but as soon as I select the company profile, everything stops at the "about:blank" page just as it does when I have automatic switching enabled.

Seems like a bug that should be fixed. Is there a workaround?
