so for another thing experiencing actually:
set up a front page with several sections, each with bg-image and set to 'cover' and 'fixed' to jump from section to section...
works well on desktop, not so well on only some mobiles and not at all on ios-devices! whereas the bg-image mostly always covers the viewport as intended, it stretches out on ios-devices far beyond whats expected - when on ios (regardless of browser) they seem to follow the whole page size and not the viewport! so this messes things up completely on ipad etc.

tried with several tweaks already but cant get close to whats indended so far... so in fact i am asking for a proper (and maybe best) way to solve this for the elementor sections! (in case this could not be solved -or served- from within elementor itself).

thanks in advance.
