It works fine on my Lenovo Yoga. If I keep my finger on the screen and move over the buttons they get a red outline (hover effect), and when I release my finger it counts as a click.
Keep in mind that once I’ve clicked somewhere on the screen, the mouse cursor is still there but it’s turned invisble by Windows.This means that once I’ve pressed the back button, the button in the left corner is hovered since my invisible cursor is still placed there. The moment I touch the screen elsewhere the red hover effect vanishes.
If you need anything else tested just let me know
