I got the missus some Airtags, ( i dont have iphone) and i chucked one in my golf bag when i went on a trip to interstate.
While i was away, the last tracking event of the airtag was at home. well i thought maybe the airtag is not detectable when its inside bag.
But as soon as i arrived home, her iphone picks the airtag, despite it being inside my golfbag, and inside my travel case in another room.
its impossible that passing through 2 airports and returning, train rides, hotels and golf everday that i didnt pass by a single iphone user, i have no idea what gives.
possibly its a good thing she cant track me - but that wasnt the purpose of the test run!
