Basically the button does not work for us.
We have been wrestling with this for over 3 months now and have a support ticket open with PagerDuty - the problem is compounded by the fact that apparently the chat functionality is supplied by a 3rd Party (Olark). We think we’re finally getting somewhere, after intensive investigation at our end it looks like there are calls to various analytics and web ad URLs which our company proxy is not allowing. This has been evidenced when running Chrome Developer Tools we have seen various URLs with a 403 error in the Network tab – at each browser refresh there is always a facebook one, plus one of the others (these tend to be different each time).
We’ve fed this back to support and are waiting a response from the Engineering team.
I’d bee interested to hear if anyone else has experienced this problem and what they’ve done to overcome it.
