I see you’re trying with the sci-fi player. Does it work with the fantasy player? I just tried it now, not even logged in (using one of the demo soundsets), on the fantasy player and it works WITHOUT “access in background” checked. With the online player I need this checked, but it doesn’t work at all with the fantasy player when checked.
I just installed the SciFi player and tried one of the demos. Didn’t work; get a popup saying I need a new app to open the link.
