Hi, I reported this so many times, so I am not sure is not here. Reported on 30th november 2017 to support, and several times through Facebook (PM and groups) Look there for more info.
The tracking code clash on my tests with:
  • Thrive Architect
  • Viral Loops (the easiest to test, as the popup button does not appear).
  • Any other popup code you have on the same page.
You wont see the problem if you are logged and you wont see the problem if you use incognito.
Try with firefox with a standard session (with cookies) and try with IE or EDGE and you will find the issues.
