I'm a Google Trusted Streetview Pro. I got my street view badge last year July (2016) and noted that I have no access to the Google Street View Trusted Group to learn, participate Hangout training, etc. (https://groups.google.com/forum/#!forum/street-view-trusted-en).
Also, I'm not allowed to check any posts and when I try to access, I'm notified that "You must be a member of this group to view and participate in it. You cannot view this group's content because you are not currently a member"
