Bottom of screen cut off on iPhone X

I have an iPhone X. The screen is often cut off at the bottom, especially when there is a text to write an answer. I’ve gone to the zoom options in settings in both display and accessibility and zoom options are all off and that doesn’t change anything at all. Why is the bottom of the screen often cut off, especially when there is a text box and I can’t even see what I am typing or a bottom box that is very hard to click on?
