This use case has been covered since these products launched.
Apple Find My to Apple Find My network got notifications. Android Find My Device to Android Find My Device got notifications. And if Android users installed Apple’s Tracker Detect, they got notifications.
Now cross platform tracking will happen without the user having to download and install an app.
If you were stealing bikes, and didn’t have something like Tracker Detect installed on your Android phone, you’re not the smartest crook.
