Is there a technical reason why this can't work with Apple's Find My network, or is it just that they don't want to work together? Using the "Unknown Trackers" feature my Samsung phone can scan for nearby AirTags and tell them to play sounds.
The feature that lets you ring nearby trackers is actually standardised between Apple, Google, Samsung and the others. It goes by DULT - Detection of Unwanted Location Trackers.
The crowdsource networks are not compatible.
