Thanks Ears. I am now able to find the manual settings and add my IP address in. My problem was that if you do not swipe in the first few seconds, there is no input possible on the app screen, only kill and start again. I got in and the app is working ok, as the interface already was through the web. I wanted the app for others in my household to use who are even less tech literate than me.
Slowly my Pi4 is turning into a usable music streamer and I am happy
