Finding AirPlay symbol on new iPlayer iPhone app
For anyone struggling (as I did yesterday) to activate AirPlay when using the new BBC iPlayer iPhone app...
... start your radio/TV programme then press the iPhone 'home' button twice (rapidly) and then sweep the menu to the left until you see the AirPlay symbol and press it.
Everything else (YouTube, iPlayer via Safari, iTunes, TuneIn Radio Pro) has an AirPlay symbol automatically appear, but not the new iPhone iPlayer app.
I'm sure you all knew this already, but I posted just in case.
