WifiConfigStore.xml moved locations in in Android 11 and 12. The paths are listed below.

/USERDATA/misc/wifi  - Android 10 and below

/USERDATA/misc/apexdata/com.android.wifi/  - Android 11 and 12

Both files are stored in regular XML (non-ABX). For Android 11 and 12, it still contains Wi-Fi information (BSSID and password). It contains the randomized MAC address, which is seen by Wi-Fi access points. This file may have a timestamp of last connection (NOTE: could be used to put device in a location at a specific time - seen in Samsung A30 running Android 11…this is NOT seen in the Pixel 3 on Android 11 or 12).  For Android 12 it contains actual Wi-Fi MAC address.
