** Chance Input Handling to Input manager
* On EventSystem remove Input System component and Add Standalone Input Module instead
TomasD: Workaround:
** After launching the app
** Run scrcpy ([https://github.com/Genymobile/scrcpy/releases)] on PC
** Android screen will be shown on PC
** Tap with Mouse on Button it will get clicked
** Tap on Android device screen on the button, tapping starts to work.
** Probably something's incorrect with Input System UI module.
