I do not understand if that’s how it should work (but it seems strange), or just does not work well.
If I have a theme, not enabled and that is not a component of other active themes, the preview button does not work, or rather, it works but opens the site as always, without let me see the preview of that stylesheet.
I also tried with stylesheets used as components of other (active) themes, but the result is the same.
Then, if I go to the stylesheet and click on “preview” without editing anything, just as described before, the site is loaded normally, without showing only the preview.
For practical purposes, the preview button does not serve anything at the moment.
Preview works only if I change something, click save and then the preview button.
Then I wanted to know, how do you share the preview with other people?
I often find myself in the situation of having to show a work in progress to decide with my team how to go ahead.
I first shared the preview link with them, but now that the preview link is no longer available I have to do a lot of screenshots and often they are not enough to explain the changes made, because they can not see them in “action”.
