I don't have AirPlay icon on my iPad

Swipe up from bottom of screen to active Control Center (tap to enlarge image)

To use AirPlay, you need the following:

1. iPhone 4s (or later), iPad 2 (or later), iPad mini, or iPod touch (5th generation)

2. Apple TV (2nd or 3rd generation)

3. AirPort Express

4. Wi-Fi (802.11a/g/n) network

If you don't see the AirPlay icon in the Control Center:

1. Turn off router, Apple TV and iPad

2. Turn on router and then wait 30 seconds for it to complete start-up process

3. Turn on Apple TV and then wait 30 seconds for it to complete start-up process

4. Turn on iPad (wait 30 seconds) and test AirPlay

I have the same issue, my airplay icon is missing from all my ipads. IOS 8.1.3 Apple TV 2nd gen. also has latest software update. Looks like this has been an issue for quite some time. Really disappointing to see that no fix is available and Apple has not seemed to address the issue.
