Workspace ONE UEM (AirWatch) Console 9.1.1
An admin is able to update an existing admin account with the same username as another admin account, which results in two admin accounts having the same username.
Note: This only impacts On-Premise environments.
A patch installer is available with instructions on the Resource Portal at the following link: 22.214.171.124 Patch Installer.
This has been resolved in AirWatch 9.1.2 and 9.2.
