Problem after ios 9 update

I have an iPad 3 (with 30-pin connector) , djay 2.7.10 and ios 9.0 …
No problems with the lastest version of djay 8, but after update to ios 9.0, my ipad no longer recognize numark idj pro.
Why ???
I’ve tried so many times, so this is an algoriddim/numark problem.
Please fix it.
