installed new release. Group extra tab if you are a WP ADMIN shows fine. Tested with my subscriber user profile and tab does not show up. Change the same user to a WP Admin and tab shows up. User role in group does not make a difference. Uninstalled latest release and went back to last release and all is fine. 4 hour detail to figure out it was the most recent update.
Thought you would want to know. Should be easy to replicate.
