When we use the shortcode for the layer slider, for instance [ layerslider id=xxx ], we can see in normal browsers the slider functioning properly.
But. When we use the same slider, with the same shortcode in a widget (on this page in the footer) it functions differently when you see the page on iOS iPad or iPhone.
The slide shows up, disappears instantly, wait 5 secs, next slide shows up, disappears instantly, wait 5 secs, next slide shows up, et cetera.
On Android, Windows etc. on desktop it functions alright.
How can this be (iOS related) problem be resolved?
