Not sure if anyone else is getting the notification on phones or tablets. But, I'm getting a notice from mine that states rv.net has their certifcate expired or something. This stuff is over my head. ...
The problem is that GS has not secured all their web sites. As of a few months ago, all the browsers are requiring HTTPS//.... for the web pages. Your browser is seeing that the URL for rv.net is only http. Once GS get's it's act together and updates it's security certificate and the URL changes to https//..... all will be well with the world.
