Inspectlet attempts to intelligently guess what's the best place to store cookies to maximize support for subdomains, but if need cookies to be stored elsewhere than the default location you can manually set the cookie location:
__insp.push(['cookieLocation', ".inspectlet.com"]);
The above line of code needs to be placed in the same block as the main Inspectlet JS code.
If you have any questions about how to change the cookie location in Inspectlet, please don't hesitate to reach out to us at hello@inspectlet.com!
