Hello,
This footer navigation is only appears on iPhone DiscourseHub and PWA (without the arrow down button) app. It is useful eg.: if you added more site to the DiscourseHub app then you can close the site with the arrow down button and go back to the added sites list so you don’t have to close the app to switch between sites. The rest buttons performs clear action. There is also an iPad version the difference is, on iPad this footer nav is on the top.
You can hide it with adding this to a theme component ![]()
Mobile / CSS
body:not(.footer-nav-ipad) .footer-nav {
display: none;
}
