Reply To: Mobile Sidebar – Scrolling down fast shows empty space at the bottom

Hi,

This issue is caused by a floating element of the browser interface that is showing or hiding on certain swipe interactions. This behavior is also visible in your video:

https://prnt.sc/aYuIDiMQgVJ8 – top URL bar and bottom navigation bar are visible. The viewport size is smaller.

The size of position: fixed theme interface elements as “off canvas sidebar” or “background overlay” depends on the site viewport size. As you see from your video and previously provided screenshots, the size of the site viewport is different when the top URL bar and the bottom navigation bar are visible and when it’s hidden. Unfortunately, currently, browsers with floating interface elements are providing newly updated viewport sizes only after interaction with the browser is ended and because of this, this issue cannot be fixed by the WordPress theme itself.

Kind Regards
