As a user, I've been hit several times missing calls and notifications when I was expecting them.
I've just figured out why that is - its because iOS 16.1 is automatically setting Smart Activation to on for Personal Focus.
So I kept missing phone calls because the iPhone had been turning on Personal Focus when I was unaware it was. As well as blocking calls, it also doesn't display any notification. (I never use this focus feature, I didn't even know it existed until now, so for it to be enabled by default is absolutely ridiculous behavior. This is iOS 16.1 beta yet but its so close to the release date of 16.1 it must be the final behavior).
Now with my developer hat on, I would like my application to detect if notifications are being suppressed due to a focus's do not disturb. Is there an API available for an app to determine if a notification has not been displayed to the user due to this for non communication type apps? Just a regular app that receives user-directed push messages and needs to know if they were displayed to the user.
