Hi Mike,
Thanks, I’ll give it a try on our site and come back with the result, but as it is also showing on your demo page, how can I disable a plugin on http://kriesi.at/themes/enfold-landing-page/ ?
;-)

Edit: disabled all plugins on our site, this problem is still here.

Dear Victoria,
Thanks for your answer and your effort. Unfortunately it is not what i mean. The behaviour is correct, or at least as I expect it on android default browser but buggy on Iphone 6/7 and on firefox for android.
In private area, there are links to images of the same testing page with android default browser:

and with the firefox browser for android. Problem also shows on Iphone 6 and 7

This problem appears only if we set the color section -> section background -> background attachment to parallax.

Do you have a clean demo page with a parallax effect on a background image of a color section that I could test to see if the problem comes from other code from us or not ?

For now on the homepage we made two identical color sections, one with parallax and the other one without, and hiding / showing using display: none / block with .avia_mobile
