How to change text size in the App run on IPad Pro 12.9 6th generation

Question

I got issue on the text size is the way tooooo small to my little kids, the eyes hurts.
But in my ipad, I tried every way in setting by changing "text size" in "display & brightness" in Settings, and I also tried to use "Text Size" in "Control Center", it only works for the content in "three dots" top right. The text size on questions and explaination and editting place is still small, not any updating.
I also tried to zoom by two fingers, it does not work ......

Please let me know how to change the size on the Ipad pro App, Thanks!

Sending an email to [e-mail] is probably the best way to solve this.
I'll also pass this post onwards and see if anyone has an answer.
