I have noticed that activating the Google Doc Embedder plugin the google ads does not appears until the embeded document is showed.
In addition, I have also noticed an increment in the following error that appears instead of the google advertisement: Unable to resolve the DNS server address.
I load the <script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script> only once in the head secion and then I have placed a google adsense before the Google Doc Embedder shortcode and other after.
Anyone else has noticed something similar?
Best,
Pablo.
