Yes. Any version of White Label equal to or higher than 2.0.0 is compatible with WordPress Multisite network installations.
Notes for Multisite Users
White Label will allow you to choose White Label Administrators. These Administrators set rules to limit what plugins, menus, and other settings that regular Administrators and users can and cannot see.
As a Super Administrator of a multisite installation, you will bypass all of the White Label rules. Each multisite can have its own login design and setting.
Super Administrators will not show up as White Label Administrators in the settings. Super Administrators have full access by default.
