I've got an old Airport Express (A1088). I can Airplay to it from my iPad Mini Retina, My iMac on iTunes, an iPod 4th Gen, but it doesn't appear from the Airplay list on an iPhone 6 & iPad Air. All iOS devices are running iOS 8.0.2 barring the iPod which is limited to iOS6. Airplay does work from the iPhone 6 & iPad Air to my Apple TV, but the AE just does not appear. Any thoughts???
