Not connecting me to multiplayer on iphone 6 iOS 9. Not detected.

It says on my minecraft that its version 0.12.1 alpha???
Wouldnt let me send this unless i had a valid version!!

When i try connecting to multiplayer it comes up 'Minecraft PE not detected.' Which is confusing as it all worked fine until i updated my phone to iOS 9.

Before i used to be able to connect no problem. No hassle. Now everytime i try it always comes up 'Minecraft PE not detected' i have emailed to makers of multiplayer app many times. But had no responce
So thought id give yous a try as im desprate to get back on multiplayer to play with my nieces who live the other side of the world.

I think that the problem is something to do with the app not staying open properly to go online.

Many thanks.
