multiple devices with Volumio app

I’m slowly working thru to getting my multiple room system going.
I have 2 devices and I can control them thru my web interface. However I would like to control thru the Volumio app.
It only sees one of the devices. What am I missing? shouldn’t I be able to switch devices using the app?
Thanks

Simple question. Should the volumio app control multiple devices?
Mine only sees one. Maybe this is a feature to come?
I have a Volumio device in the garage and another in the bedroom.

If you use the official Android app, just scroll down?

If you use a different app, well…
