Redirect to Okta site on mobile fails to open Okta verify app

I’m attempting to add Okta SSO support to the Android client for our web app. The Okta Mobile Connect documentation makes it seem like a redirect to the okta site ( from a mobile browser will be redirected to an Okta URI (okta:// or oktasso://) and then open the Okta verify mobile app. I have not been able to get this behavior, am I missing something in the documentation?
