i cant get an input signal with my apogee jam on latest ios 8 / iPad Air. GarageBand does work out of the box with same setup.
Ill provide 5 stars again, if this gets fixed.
Great app, but not useful for me at the moment.
### update ###
thanks to the fast support!
On iOS 8 you have to allow jamup microphone access. iOS setting -> privacy -> microphone.
The app hasnt asked me in the first place for permission though. I had to reinstall from scratch.
Anyway, everything works fine now.
