Mobile Site Loading

Hi
When I’m looking to my site from Chrome , there is a style while going down
(a Loading Style)
but when I’m trying to look in my Mobile browsers , when I come down the stylish loading is not working
what should I do right know?
this is my site
https://www.iranfollower.ir/Otlar
dont forget to add /Otlar to that domain beacause iranfollower.ir is another site
