I tried a bunch of things and came to the conclusion that the problem is most likely due to fullpage.js . The section is a slider and when you click on input, the keyboard opens and the system adjusts the keyboard to the bottom of the input, but there is nowhere to go down. It turns out that the content just goes beyond the screen and everything turns white. It is necessary to somehow allow scrolling and leave additional space for scrolling, but maybe someone knows how else to solve the problem?
