Squeezebox app not working

After installing the Squeezebox app it is searching directly my Logitech Squeezebox devices. But it is not finding one. You have to give in the Squeezebox server first, but that screen is not shown first.

Can someone help me out? @MarkT?
Is it possible to set the settings somewhere elsen?

A little off topic: I hope there will be a Squeezebox app for Homey v5
