Yesterday was streaming Hulu from iPhone 4S to Apple TV2 just fine. Today I went to do the same, scrolling to the right but all that is there is the volume bar and no AirPlay icon. Anyone know what to do? I checked Apple's help page, on the safe WiFi network, AirPlay enabled, I restarted my phone, and still nothing! Anyone have any other ideas? Software up to date as well. Like I said, I just used it last night.
