Ads very disappointing…

I was a happy user of this plugin with not much to complain about…
However since once of the last updates, some ad banner for Yaymail started to appear… the banner you can just close it, I would tolerate that: a free plugin needs to survive.
But on top of that, it also adds buttons linking to install that yaymail plugin right into my woocommerce admin email settings, links that I cannot remove. And that I am sorry, I cannot accept.
Too bad, functions are working but I will have to find something else that does not force some ads on me and modify other plugins admin area…
