In case this is driving you crazy as much as it did me, there is a caveat for which Windows thinks we use a stylus instead than fingers. This breaks Gestouch functionality and it is inconsistent (10% of taps it does work).
I explain this in Adobe forum: https://forums.adobe.com/message/10850903#10850903
In order to have gestouch work again for taps, you have to comment where it checks for isTouchPointCanceled in NativeInputAdapter.touchEndHandler().
Cheers and happy new year to everybody.
