Compared to other OSes people update iPhones really fast. Apple really encourages updates (new emojis!), including automatically updating things unless you stop it.
Given this is public beta one we may see the release near end of March (total guess on my part). Point releases don’t tend to have too many betas. And Apple ID itching yo get the HomeKit new architecture bug fixed soon and that’s in 16.4.
Does anyone have any sense of how long it might take for this get out of beta and widely supported by iOS/iPadOS devices?
