Djay 2 crashes when switching from turntable to waveform view on IOS10

Since upgrading to IOS10.0.2 last week I have had the same issue occur several times - the DJay app (version 2.8.4) crashes when switching from the vinyl view to the waveform view. I have sent the crash reports to you when prompted. I can’t seem to replicate this now but it happened when using with the Numark IDJ Pro.
