> In Android 10, MAC randomization is enabled by default for client mode, SoftAp, and Wi-Fi Direct.

It randomizes per-SSID, so you get a random MAC per SSID you remember on your phone, this ensures privacy while not breaking DHCP / static IP etc.

What happens if you hit forget network? Does it also forget the MAC address for that network so you use a new MAC if you join the network again?

Just tested on my home network and it picked a new random MAC.
