My iPad's MAC address seems to have changed with the iPadOS 14 update. Is this normal?
Shortly after posting the question, I found out that there is a new feature in iOS/iPadOS/WatchOS that changes the MAC address to an individual private one for every wifi network. I think I will be turning it off for my own wifi networks.
It seems to be turned on by default.
