I have a few air tags tied to my work iPhone. My main phone is a pixel and I didn’t even realize you could connect them together. As soon as you open an air tag near an iPhone you get a little pop up prompting you to set it up and off you go. They only update location when they come within range of a new iPhone but that’s pretty constant anymore.

My daughter is on the spectrum and I have one in her bookbag. It’s cool sometimes being able to watch her bus ride to and from school as she passes by different phones 😂
