Mist documentation shows a WAN menu under the Organization for us to manage SRX devices and similar. I do not see this in my Mist Organization menu. Also, when I try to upgrade my SRX, I don't see the Utilities option. Why these options are not showing for me?

Several Mist GUI menu options are missing.

These options missing are related to a lack of licensing and/or to the user role assigned, because the user role may not have certain rights.

You may want to check your licensing and your user role.
