If you're using Content Security Policy in your web application and are installing SatisMeter via a HTML snippet into the site using Content Security Policy the following needs to be added to your {Content-Security-Policy} {meta} tag:
{default-src 'self' 'unsafe-inline' 'unsafe-eval'https://app.satismeter.com}
The resulting meta tag will look like this:
<meta http-equiv="Content-Security-Policy" content="default-src 'self' 'unsafe-inline' 'unsafe-eval' https://app.satismeter.com; img-src https://*; child-src 'none';">
