In some environments after upgrading to AirWatch 8.2, the Enable Containers checkbox is selected under Settings > Devices & Users > Android > Agent Settings > Samsung Knox. Normally, if this settings is being utilized there will be a value entered for Knox License Key. However, after the upgrade if you see this is enabled but no Knox License Key entered, or you have confirmed that you do not use this configuration, then disable this setting and save the page.
If this setting is incorrectly enabled, it can prevent certain Android devices from enrolling properly.
