Ver 2.8.6 ruined my ipad..

Great app and use all the time. Updated to latest software using ipad 3 iOS 9.3.5.
At first all buttons lagged by a second rendering use of app useless. Using same song on both sides now the app NOW auto corrects until its beatamapped and in sync. If play one song on right side and cue point 1:00 then start. Left side with same song slightly ahead to give a ‘back to back’ or chasing effect the silly update now auto corrects this. why? The useless djs whom cant use pitch properly have been catered to yet the people with skill and talent know when a song is not beat matched. Anyone explain why this is like this. Its annoying, I did it easily before the update.
