Hi,
(Just back from holidays…)
Through an android emulator I get a similar problem as you decribe.
When I click on the “radio” button a next song is fetched, but the orange “radio” status is cleared and disappears.
So the next time the song ends, you are not in “radio” mode and playback stops.
Is this similar as your problem?
(I think I can resolve this issue in the next release)
Regards,
Lieven
