Why don't I see "Share demo" and "Generate a license" on my training page?

On are on the Administration page of your training course and do not see the Generate license or Share demo buttons?

There can be four causes:

• This feature is only available from 3 version of your Mission Center. If your version is older, contact your project manager to request an update for your instance.
• This feature must be activated by Teach on Mars teams. Contact your project manager to request activation.
• Your training course may not have been published yet and must therefore be published
• The training course may itself come from the “Off-the-shelf content” feature and cannot therefore be shared with a third-party Mission Center.
