On Vive controllers with 2.7, neither trackpad presses nor menu buttons work. Only grip to show laser pointer and trigger to left/right click depending on laser color work.
On 2.6, left menu button showed game menu, and right menu button was VR zoom by default. I also had custom bindings on trackpad presses in UI Layer to left click / right click, scroll knobs without having to twist your hand like crazy. 2.7 broke the ability to bind (you can bind actions to Vive Controller buttons but they never get triggered). Please bring back the 2.6 behaviour, or better, make VR Controls the X-Plane way .
