iOS app keyboard spacebar returns character 'a'

[art-mixer]

Hi

I have just installed TV 10 on my MacBook Pro and downloaded the app to both iPhone 5S and iPad Air 2 . The remote connection between MacBook Pro and both devices is all working fine except...

when using the keyboard within the app (iOS 8.3 on both devices) all the keys/key combinations work as expected except the spacebar. Instead of a space it returns the letter 'a'. Connecting a bluetooth keyboard also causes the same issue.

Does anyone else have this issue? Would anyone be able to help?

Many thanks
