Note that iOS 26.4.2 turns on Stolen Device Protection, causing a delay before some functions become operative. If you have problems with your device not recognizing that you are in a familiar location (in my case, my truck) you may want to turn this feature off.
Stolen Device Protection is only of use if your phone is stolen by someone who knows your password AND is not in your home or otherwise familiar location.
You can find Stolen Device Protection in Settings/Privacy & Security
