Found the following message in my AdSense control panel tonight.
Your site's mobile-friendliness is now considered as a Google Search ranking signal.

Just a generic message, I think. My sites are now all mobile responsive and Google's own tool gives them the thumbs up.

Wish I could get rid of the notification in the app. My sites were mobile before Google was, fer crysakes.

They'll come up with an equally-unhelpful message to replace it soon enough I would venture.

Yes I got this message as well, however when I go to the Google mobile friendly test website, it's telling me that A couple of myy websites are not mobile friendly because firstly, the links are too close together, and secondly, content is wider than the page. Can't understand why, I've checked my website iPhone5 and it looks absolutely fine.
