AirDrop works very infrequently for me. I will open AirDrop and not see someone who's sitting right next to me, or then I'll send them the file and it'll get stuck on "waiting" and they'll never get the notification, or it'll send some of the files then seem to get stuck partway through.
This is all with modern day iPhones, like iPhone 15 and above, and just using it in what should be the happy path. I'm actually really surprised every time I hear people say it's so good, because I almost always have to end up just imessaging a picture instead and finding that it works much better.
