Site Administrator Unable To Create New Groups After Installing Or Upgrading To Tableau Server 2020.2

Issue

After installing or upgrading to Tableau Server 2020.2, site administrators are unable to create a new group due to the new group button missing.

Environment

Tableau Server 2020.2.0 and newer

Resolution

As a workaround, the site settings for Managing Users can be modified by the Server Administrator to allow Site Administrators to create groups.
1. Log in to Tableau Server as the Server Administrator
2. Navigate to Settings > General
3. Under the Managing Users section, select "Server and site administrators"
4. Click Save to save the changes

Note: These settings are specific to each individual site. If your Tableau Server environment has multiple sites, it will be necessary to make these changes on each site.
