Hi all. New to air tags, have only had them since summer.

My husband and I each have air tags on our keys. Today he went into a store for 5 mins, and I stayed in the car. He left his keys behind.

I just noticed now, an hour later, that I have a notification of an air tag tracking me. The mapping is the same as where he went into the store. When I choose “play a sound”, from inside our house, my phone says it can’t detect the AirTag. When I choose learn about this AirTag and bring his AirTag close to my phone, nothing happens.

We are a family in our Apple accounts. Would family members receive this type of notification? If so, why can’t my phone detect his AirTags now despite being 10 feet away, and then directly in my hand?
