Newby Qobuz Spotify question

I have registered to Volumio with a Virtuoso plan. Planning to use it with a Raspdac to play Qobuz. I use an IPhone X 13.1.3 and Internet Explorer to connect to myvolumio.

With IPhone a can’t log on to Qobuz, with Internet Explorer this is possible.
I can log on to Spotify on both.

However, both Qobuz and Spotify don’t appear in the browse page. So for now Volumio is useless. How do I get both apps in the browse page?
