Problem with VR on safari !?

[Pierpaolo]

Hello everyone,
I create couple of Vr for my website : http://www.lazzarinidesign.net/LocalMotorsRallySpider.html I was used to visualize with all the browser including mobile device and they work fine until couple of days ago.

Now if I access with the Iphone on safari I can't rotate the models anymore !
Can somebody help me to understand why?

Please help me !!!
