After upgrading to 18.104.22.168 version i jave the "Premium Support" link to Yoast support in almost all my plugins.
I tried disabling all my plugins and let WP SEO to be the only one active. And the premium support link is still there.
The only way to make it dissappear from all the plugins is disabling the WP SEO plugin. So there´s a problem whith this version.
Please help, it´s not urgent, but it is annoying.
