Please remove that forced integration of a commercial third party without knowledge.
I don’t want wistia to know if someone uses the admin area of any site.
As @swinggraphics stated, there is no need to force loading of all the guided tour stuff for all users.
BTW: I get following error caused by the wistia integration (Latest Chrome with default settings):
GET https://fast.wistia.net/assets/external/E-v1.js net::ERR_BLOCKED_BY_CLIENT
Please create at least an option to deactivate it by removing it from DOM.
Or just
Remove the Wistia iframe.
