Slider arrows not showing on iOS devices

Hello,

Still loving the theme and my site is nearly finished and ready for launch. However I have two big problems with the siteorigin slider.

Firstly, the slider does not show arrows to navigate on iOS devices. How can I fix this?

Secondly, I am trying to build a gallery page with multiple sliders on multiple rows. The issue is that the sliders keep overlapping each other on the user’s end, no matter how many line breaks I insert. Any fix for this?

Thank you
