Note from Microsoft
Microsoft Intune will no longer collect Wi-Fi MAC address for newly enrolled personally-owned work profile devices and devices managed with device administrator running Android 9 and above. Google is requiring all app updates to target API 30 by November 2021. With this change, Android prevents apps from collecting the MAC address used by the device. For related information, see Hardware device details.
Network access control with certain NAC providers and third-party VPN providers may be affected. This may impact the ability of enrolled devices to connect to a corporate network. More information can be found here: Support Tip: Android 12 upgrade can affect NAC-enabled network access.
