Sidebar mobile version is very buggy

Sidebar works good on desktop but mobile version is very buggy. Tested on iOS 9, nothing shows up after clicking Share button on the bottom of the screen but links are actually there.

Tried to hide it by using Smartlayer (http://support.addthis.com/customer/portal/articles/1200473-smart-layers-api) but it doesn’t do anything.

{"follow": {"mobile": "false"}}

I had to hack it to hide it on mobile but hope to get better solution.

@media only screen and (max-width:768px){
/* AddThis plug-in bug */
    #at4m-mobile-container{
        display: none !important;
    }
}
