Doesnt work well after I upgraded to an iphone 7

I up graded to an iPhone 7 and now the app doesnt work well. I can move the cursor just fine but clicking on an item requires me to tap on my phone screen 20 or 30 times. I am guessing it has to do with the force touch? Still works just fine on my iPad 2 air.
