iOS Safari problems when clicking products

Hi all,

I have recently launched my website:

I am running to see how people behave. A big problem I have noticed is that people on an iPhone or Tablet, running Safari, have trouble with loading the products when clicking on them. It looks like Safari is buffering them or something and the pages are only showing several seconds later. Most of the time, people have already clicked on them again, or an other product and then all of a sudden Safari loads them all at once. This will result in the customer landing in a loop where it keeps switching between products.

This recording gives a good example of the problem. You see people tapping, but nothing haps until several seconds later.

Does anyone have an idea why this is happening and how this can be fixed?
