Glen currently AAM does not have Multisite add-on available for the version 6.
This is something we are planning to add with AAM 6.1.0 release. We need some time to review all the changes that WordPress core introduced to Multisite support since 2015 (this is the last time we've checked WP core multisite implementation).
As of today, this is the following list of features that we are planning to implement:
- Ability to navigate between sites from the main network site (the same way it was done in AAM 5 and Multisite extension);
- Ability to automatically sync roles across all sites;
- Ability to automatically sync access settings (Backend Menu, Redirects, URI Access, etc.) across all sites;
- New Access Policy resource SITE;
You are more than welcome to request any other features, however, we can't promise to deliver them in the first iteration.
