But ... I'm Android.
The new update to Google's Find My Device app has a facility to notify you if you are 'being followed' by a tracker tag - this update was delayed for a considerable time because it needed to be compatible with both Apple Air Tags and the newer Android tags (from Chipolo and Pebbledee).
It's only really come on stream in the last couple of weeks.
I think that the idea is that you get a notification if an unknown tag is with you over a specific time.
I'm guessing that you are Alpha Testing the functionality in the real world.
I only know this because I've invested in a pack of the Chipolo Android tags which have just been delivered.
I'm finding it hard to recommend them just at the moment - the Google Find My Device app is... poor.
