Just tried it. Marked two stations (which did not connect) as favourites. Did something else, came back to this app, tried to play the two stations and kept getting the "go premium" publicity. Could not play them again. So this seems to be a "one-use" app. Note to developer: how can people evaluate your apps if you do not give them full access for some time? Good way to lose clients. Bye!
