What should I do if iOS 17.3 doesn't recognize my home as a familiar location?

Same had this problem 88888 times and don’t know how to fix it

So frustratingly ridiculous. And typical Apple silence and zero support.

I'm on 18.0.1, and still having this issue.

Your location is end-to-end encrypted. Apple can tell you are in the same one, but not where it is.

Same it’s soo anoying when you have to wait one hour to change some settings because “your not in a familiar location” but I’M FLIPPEN AT HOME

Same for me. I’ve had this device for over a year and I come home every night. Yet sitting in my living room is not a familiar place. I looked into my settings and found 3 recent examples of familiar places. One was work, one was a fast food place I had lunch at yesterday, and one is a store I was at for about 30 minutes. BUT STILL NOT HOME.

Come on Apple this is ridiculous.

This feature just isn't ready for prime time.

I spend like 99% of time at my house, in a location with ample wireless and cellular signal, and yet it's not considered a "Familiar Location" by Apple.

Today, I had to reset my passcode, which required me to wait an hour. On a lark, I opened a chat case with Apple. The chat technician told me that, because I wasn't at home when I set up my phone, my home is not considered a Familiar Location.

I politely informed him that, first of all, I was at home when I set up my phone. Secondly, I told him, the Apple Support page (About Stolen Device Protection for iPhone - Apple Support) states that Familiar Locations "typically include your home, work, and certain other locations where you regularly use your iPhone" and that there's no indication that it's related to the location where you set up your phone.

He thanked me for checking the support page, and then escalated to a support technician on a call. This technician informed me that the entire Familiar Locations feature is automated and there's no way to modify it.

So, it's an automated feature in a black box, but it doesn't actually work. Which is just another way of saying that it's broken and probably not worth enabling. Bummer.

Yes, my contact card lists my home and work address.

I'm very glad that the feature works for you. But it's not working for a lot of us. And, unfortunately, as per Apple technicians, there's no current fix. Setting your home location via your contact card, or via any other manual process, does not impact the Stolen Device Protection Familiar Locations.
