FCC display issues on Ipad

Hi there!
I love our camp so much and I constantly feel beast starving when I’m not able to code here anywhere I’m. So I bought an Ipad to be more productive. But the problem is I can’t change the size of those free sections like on PC dragging this navbar by mouse expanding or reducing those three windows with task description on the left, code field and a webpage prototype on the right. Literally when I touch the screen trying to move these widows dividers left or right nothing is happening (( I tested on IPad 2018 in safari and in chrome.
Seeking for your help, friends!
