Mockup is currently unavailable

I can not use mockup feature, it says 'mockup is currently unavailable' Does anybody see this? If so how can I solve it?

Make sure you do not post anything from a pre-release version, as that violates the confidentiality agreement.

Mockup is in the public beta now, Mike, though users may be better off posting in prerelease channels as the users there will have more experience with new features.

@abdullaho87486203 can you show what you have selected?
