|
|
// The main issue is, that we render different components based on the view port - which means that
|
|
// the server-generated DOM differs from the DOM that would be rendered on mobile devices.
|
|
// We therefore completely ignore the pre-rendered DOM on mobile and let the client render.
|
|
// To solve this root of this issue, we need to remove the conditional renderings that check "isMobileViewport()"!
