supsystic on "[Plugin: Photo Gallery by Supsystic] Horizontal Scroll Gallery scrolls very very slowly on mobile"

Horizontal Scroll Gallery scrolls very very slowly on mobile, it takes forever to scroll... I'm using a iphone 4.

Is it just me or it that how it is? What can be done?
Thanks.

I have only 6 images in the gallery. Does this have something to do with the scroll being so slow?

Hello!
We will try to improve Horizontal Scroll on mobile devices in next version of plugin.
I will inform you about the result.

Hi, apparently it doesn't scroll on tablet, iPad, as well. Looking forward to your update soon! :)
