Which membership requirement for chess mentor?

The webpage here http://www.chess.com/membership?c=chessmentor says that platinum members get 5 lessons a day.  However when I click on the platinum "choose this plan" button I get a popup that says chess mentor is only available to diamond members.  So which one is it?

Thanks

I have the same problem. Just signed up for the Platinum service. How do you get to the lessons??

Normally you access it from the "Learn" tab at the top of the page, or from the "Lessons" tab if you're on your phone.  As a non premium member I'm still able to get one lesson per day. I was gonna pay for the platinum membership right before I recieved a popup saying chess mentor was only for diamond members, even though it still advertises 5/day right there on the web page, and 3/day for gold members. Are you able to access the lessons at all?
