Number of times I've had a true positive alert from Apple's new device tracking notifications: 0
Number of times I've had false positives due to intermittent connectivity issues with my airpods or from my partner using mine: over a dozen. I'm this close to disabling all of these features
Everything else? I had my iPad in the backpack I was wearing get left behind. Same with my AirPods. I’ve turned those things off and just put an AirTag in my backpack.
That said, I already had two extra air tags since I got a four-pack instead of buying two separately.
This is a general problem with proactive alerts related to rare events. How many "OMG, you're separated from $X" alerts am I willing to put up with for the one legitimate "You just left $X in the restaurant!" alert.
