Multisite activation failed to add users to approved list

Aloha! I am attempting to use the Authorizer plugin on an existing multisite installation and have run into some problems during the initial activation of the plugin. We noticed that the plugin doesn’t always add the existing users of a site within a multisite network to the approved users table. (On some sites in the network, it appears that the function ran correctly. But in other places it was never run. Or, at least it did in our specific hosting environment.)

Two questions:
1) Is there a setting that I missed that would guarantee this to happen? If so, is the best course of action to uninstall and possibly reinstall the plugin with that option set properly?
2) Is there a DB option (or options?) that I can update manually with WP-CLI that stores users in the approved users list?

Appreciate the response. The plugin is fantastic!
