yunohost + navidrome --> subsonic/airsonic client trouble

Hi folks, I have yunohost running with navidrome. I'd like to connect a client to the server on my android phone (Symfonium) but I can't get it to connect to my navidrome server.

I see in the yunohost docs that I "must activate public site if you want to connect a client player to Navidrome.", but I can't find any documentation about how to do this. I thought this might refer to enabling guest access, so I added the "visitors" to the permissions...no effect.

I've also tried the airsonic-advanced app, but couldn't get it to work either. I thought I might have to port forward the 4533 port, but that didn't see to have any effect.

Not sure where to go from here...any ideas?
