the iPad Air 2 have issues with the latest 3.4.1 release.
Almost all remote commands does not respond. The only remote items that seem to get sent are the number keys. Any other key does not even seem to register you press it. (Enter, up/dn, exit etc)
Normally when you click a button there will be a small delay on the players image. That does not happen now on iPad Air 2.
But my iPad Air 1 works "okay"
Apart from that the streaming on both my iPads stutter a lot more on 3.4.1 than they did on the previous version.
