I just installed the new Analytics extra and placed the Snippet call in my template but no bit of the analytics code lands in the HTML output. (and yes - I logged out of Manager and cleared the cache)
By the way - before installing this extra I had a small chunk which holds my old google analytics code and this had exactly the same name as the chunk of the new installed "Analytics" extra - "googleAnalyticsTpl".
My chunk was overwritten without any warning by the installer. Is this a normal behavior or a bug?
OK - problem solved! I reinstalled the Extra and now it works as expected!
I think there was a problem with the previously existing Chunk with the same name.
One more thing:
It only makes sense to call the snippet cached (not uncached as in the documentation of the Extra)
