I recently noticed a bug on mobile. Whenever the player presses the menu button, it appears that UserInputService.JumpRequest() is fired.
It happened on my mobile device, an iPad.
I am unsure as to when it started happening, I only first noticed it today when testing on mobile.
It is easy to reproduce the bug. Simply hop onto a mobile device and press the menu button. JumpRequest should fire. At this time I am unsure if it fires when emulating a mobile device in studio.
