Thank you for your answer @Richard . I need the video to be fixed and to cover the whole body (100vh)
Now I found out that the behavior is down to position fixed, causing this problem in the mobile view. Using your code (or my code) with position fixed is causing this error. Without fixed positioning, everything works as expected.
Is there something that I need to know about the theme in order to work with fixed positioning? Cause I remember some issues in the past that I had with fixed positioning.
Would love to hear from you
Best, Markus
