AirDrop is a particularly egregious outlier. It’s clear that something has gone very, very wrong with that feature. Not only with how unreliable it is, which is already bad enough, but with how clearly broken that basic state machine driving the UI is. Once it has gotten into a bad state, from my experience there’s no way to get it to succeed without restarting one or both iPhones.
