For non-admin users, 2 permissions are needed to be able to promote a content view to an environment (promote_or_remove_content_views and promote_or_remove_content_views_to_environment). Filter on the first one creates a restriction on what content views a user is allowed to promote, the second one restricts what environments a user is allowed to promote to. The idea is that some users may be allowed to promote certain content views to 'Test' environment, but not to 'Production', which allows for better granularity. One negative side effect is that both permissions need to be assigned to allow promotions. Not all users are aware of it and  was raised. Maybe we could add a side note on this to Content Management Guide (or some other place if it is more appropriate).
Assigning to Zac for review.
Zac - looks like we need to add a note to the following section of the Content Management Guide to call out the permissions above, and one or two quick notes about what each of the permissions allow non-administrators to do -
