As user annoyance with the behavior boils high, Apple has finally responded, saying the constant pop-up is not how the feature is intended to work. MacRumors reader Kieran sent an email to Craig Federighi and Tim Cook, complaining about the constant prompt and advocating for Apple to treat access to the clipboard the same way iOS treats third-party access to location, camera, microphone, and more.

Ron Huang, a senior manager at Apple, joined the email thread saying the pop-up is not supposed to appear every time a user attempts to paste. “This is absolutely not expected behavior, and we will get to the bottom of it,” Huang said. Huang added that this behavior is not something Apple has seen internally but that Kieran is “not the only one” experiencing it.

I've seen this bug twice so far since updating to iOS 16 last week, and it's annoying.
