I'd already opted in to share my phone's and watch's location. It was beyond annoying that I couldn't opt in to share a specific AirTag's location, too.
I’m glad to see that they’ve seemed to upped the limit or don’t count the shared AirTags against that limit anymore.
16 seems like a lot, but if you’re traveling with a couple of items you want to track and share with your party as backup, you start hitting it pretty fast.
Mostly the usual battery/heat issues, the frequent app crashes (1st and 3rd) and the annoying hidden keyboard bugs that lasted through several public beta releases that required force quitting and restarting apps before it would show up again.
Rather than re-hash, /r/iosbeta is a good indicated of the tribulations of each release.
I'm not saying it was bugfree, just that the apps I use most were in decent shape from the start. (But I still acknowledge that you or anyone else might've had a very different experience from mine.)
