before I used to publish a site, then open the URL in a new tab and test out the site.
Now, when I publish the site, open the URL in a new tab (via the 'new tab arrow' in the publish dropdown OR manually typing URL), it seems that as long as I'm logged into WebFlow, I can't test out the site with normal settings (i.e. any embeded scripts) because the site sees me as logged in.
I'm pretty sure you dont' want us to log out/log in every, single, time we want to check out the site's progress. So this could only be a bug somewhere.
This is what I see when I open a new tab and try to test out the site.
