Change text size on ipad

Hi, I wonder how Dorico changes a text size on iPad. I was able to write a text sticked to some note, to engage an small extra stripe with text settings, even to see a box with digits…Any way if I type and confirm with OK nothing happens. Tried it many times. Yes I marked a text I would like to change…What I am doing wrong?

Double tap the text to highlight it, then double tap the pt size thing on the text editing toolbar and you should see a numeric value input widget. Then use either the paddles or the text field to input a new font size, then tap OK.

Dear pianoleo, I did exactly everything like you described. The problem is - nothing changes…A font size stays exactly as it was…I will try tomorrow it again while traveling. If I wont succeed, I will do a short video…
