WPMU DEV Missing From Dashboard - non default admin user

I installed WSD Security and one of the suggestions was to stop using 'admin' and create another named admin user. So I did. Everything seemed fine but then I noticed that WPMU Dev is not showing up on the list. I've seen some other links that said mentioned using an alt named admin being the culprit for this issue with other plug-ins.
i.e.:
https://premium.wpmudev.org/forums/topic/membership-menu-not-showing-up-in-dashboard
It mentioned editing a membership config file and adding the new admin name to it.
Is there a similar file for WPMU Dev or Wordpress in general?
Stuck for the time being....
