Good morning Ismael,
Thanks for the feedback. Please see my comment below.

Issue 1:
a- I Apparently this is an enfold issue with IOS as I can see with my Iphone muted video from other Websites (using other Themes) and here is an example: http://www.djangelo.co.uk.
So my question here: Is this something Enfold is looking for to resolve in the near future ?

b- My Web designer could not hide the video on mobile devices as per your instruction, could you please take a look in the Back-End, maybe you will find out the reason and help us with that ?

Issue 2: My Web designer followed here the instruction as well but could not succeed. Can you please have a look if I provide you the log in and password ?

Thanks and regards, Elie
