Bug with new mission solution screen

Hello,

After solving String conversion and publishing my solution, I wanted to see other players' solutions as I have used to do.
But no matter what I do, I always get this following screen: only random reviews, asking me if I want to purchase an Awesome membership.

Problem: I am already a premium user. Solutions are locked and that's exactly the reason why I bought a premium membership in the first place. It should allow me to see all solutions posted on CheckIO whenever I want.

So, is this a bug? Or buying a premium account is useless?
Please I need a clear answer on this matter.
