Well I had them two weeks ago, before I lost access to my broadband connection. Now I have the access back so to do I have the ad in the lower 1/4 of the UI.
Though I'm using the free version, but I have never minded these ads as they are much less intrusive (I don't live in the UI) than the full fat popup ads.

As MartinZ said, you or other paid users shouldn't see them:
the change is live now. so if you have the settings unchecked you shouldn't see a banner in UI
Now in the paid versions, that is was meant to be removed today.
