I use ProSites.

I installed AutoMessage via the WPMU Dev Dashboard on my site.

Clicked on Network Activate: in the WP activate plugni menu it shows as active.

On my Network Dashboard and Primary Site Dasboard it doesn't appear, nor is it a sub-menu in Settings, etc.

Any ideas where it's gone? I updated to the latest ProSites yesterday.
