Using Small Screens
Phones and tablets can be a little challenging because of their small screens. Whilst you might expect something to be somewhere on the big computer screen, it can be moved to a different position on a small screen.
Try scrolling (ie. touch and slide) up and down, and left and right *slowly*, looking carefully for what you want. It is rare for something to disappear.
Also, don’t limit yourself to always doing exactly the same thing, different problems require different solutions.
