SalesIQ Not Tracking Any Visitors

SalesIQ Not Tracking Any Visitors

Hello all,

We have SalesIQ
  1. the tracking code for the brand is added to the website via Google Tag Manager
  2. SalesIQ is showing "green" for the code, meaning it should be ok
  3. The "Track Visitors" button is on 
And yet there is absolutely no visitors tracked on the website.

Any idea why this may be?
