Hey @arminunruh .
I recognized that (after update?) my mp4 intro doesnt work on mobile very well because autoplay doenst work (anymore?!) on safari + iPhone 7 so i decided to take a gif instead.
it works but when i put my phone in landscape mode the mp4 appears?! but the layout is still for mobile (with the burger menu)
Now i removed the intro for mobile but in landscape there is still the desktop mp4 intro on my phone?!
I set my phone breakpoint to 670px so this should not be the problem?!
I guess before the update also the autoplay worked well with a mp4 on mobile - did u change anything?
