I am trying the Microbit Setup App v1.0.1 for iPhone.
It works relatively OK on my old iPhone4.
However, on the iPhoneSE it has a problem with the display size.
The result from a search is hidden behind the text on the top on the screen. If the screen is being moved a bit down by using the finger, one can see the result. When the finger is being removed, the screen moves again up, and the text again disappears.
This seems to be a problem with the automatic adjustment to screen size.
