I am running OC 3.0.2.0, few weeks ago I installed a caching extention for faster loads of the pages, it works great, until today I decided to show my friend on his iphone how fast is my website. I was not able to scroll most of the pages, yes all these pages were cahced for faster load already. The issue is only with Iphone phones, all anroid phones are ok. Once I found out the issue I tested on 3 other Iphone and they were not able to scroll. Here comes the interesting part.
I cleaned the page cache and all iphones started scrolling. Once it was cached by iphone it worked with android phone also. But when a page is cached for the first time by android phone, you are not able to scroll that page on iphone

https://ledsvetlini.com/Kak-da-izberete ... ki-za-kola - For this page I disabled caching you can check you can scroll
https://ledsvetlini.com/Signalni-krushki - this page is cahced for first time with android, if you have Iphone you should not be able to scroll it.
most probably there will be more pages that will get cached by online user and you won't be able to scroll from your iphone
How this can be fixed?
