Hi, I have a problem that prevent me from seeing live view visitors from my store on my Shopify platform . Recently I hired a guy to optimize my site in aspect of speed and performance , after he finished the job I noticed that I can't see live visitors own my Shopify platform anymore , even though on google analytics it showed visitors , of course ,  eventually I don't have a summary count of visitors either  , I tried to publish an older version of my site , and it worked just fine. I contacted  Shopify support and they told me that most probably the guy that worked on the code , had removed something from the code that caused this problem since non Shopify themes have code  for this connection . I asked the guy that made the  work to try fixing this  , but I don't think he can find the problem . Can you point me to the needed code for this linkage and where should I install it in the theme ? I can't use my older version of the site since it has some problems and changes in content . thank you 

thank you , the guy I hired fixed the problem but it’s good to know where to check . Thanks
