My site is in AngularJS, so I recently created HTML snapshots of all my content, added the escaped fragment tag to the head of all my pages (meta name="fragment" content="!"), and then tried to test to see if the new setup was working in Webmaster Tools. When I look in the source I see the escaped fragment (however, it's inverted) (meta content="!" name="fragment"). I'm not sure why that's happening or if that matters...
When I submit a URL to "Fetch as Google," Webmaster Tools returns Fetch Status Not Found. However, if I manually add "?_escaped_fragment_=" to the end of my URL, I get a success status.
So, my question is, does this have something to do with how Webmaster Tools tests URLs or have I set up fragment escaping incorrectly?
