Unable to correct writings on Ipad

It seems I am completley unable to click on a word when correcting writings. I get to the screen where two windows come up - original version and corrected version. I can’t click any word and clicking ‘new correction’ just gets me; “please select at least one symbol”.

@Kyleleitch - Yes, that functionality is not possible on an iPad. You will have to use a computer to correct writing.

Well, I guess I’ll put of being a tutor until that function is added - no computer, just ipad here!
