MRCOOL DIRECT review for Shopify Inbox

I had access to chats/ inbox but for a long time now i have not been able to access this shopify in box aka chats, I was told to reach out to tech support yet are unable to find any tech support links to help resolve these issues. fortunately i am not the only one at my company and others still have access but I do not. I can log in to shopify in box in on of my stores but when I click on a chat it errors out and then the other store i will not allow me access at all so I have to log in through my first store then try to click over to it. only for it to error out.
