itunes 11.2.2.3 airplay not working with radio
I installed iTunes 11.2.2.3. AirPlay works fine with my music library; the AirPlay icon appears, and I can choose the Apple network device to which I want to stream content. However, when I play iTunes Radio, the AirPlay icon disappears, and I can only listen on my computer. Is there a fix for this -- or do I need to downgrade to a lower version of iTunes?
