Hi Eduardo, 

we will find a solution (hopefully)!

Well, since the CSS is loaded on 3 of your Themes, its always being loaded by any portals using those themes.

To test if ATF would work without the CSS, note the 3 themes and then remove the CSS from all of them. And then give ATF a try if that helped.

Curiously, we use Roboto too, but included it into our main CSS for our portal like this:

@import url('https://fonts.googleapis.com/css?family=Roboto');
@font-face {
  font-family: 'Roboto';
  src: url('https://fonts.googleapis.com/css?family=Roboto');
  font-weight: normal;
  font-style: normal;
}

Kind regards
Oliver

GlideScreenshot and Assert Text on Page fails when the styleSheets are delivered from a different domain (CDN)

If stylesheets are delivered from a CDN, the user's browser prevents them from accessing styleSheet.cssRules with JavaScript.
