This post is from the Activity iPhone Duo UIKit Q&A.
Cold launch from a shortcut, universal link, or push is handled in scene(_:willConnectTo:options:). Diiferent functionalities also start Live Activities and reload widgets. If the device is folded, does that scene connect for the outer display, and can the geometry still change before the first frame if the user unfolds? When folded, do Live Activities and widgets appear on the outer display, and is there a separate presentation the app must support?
