Mail was working well in iOS 16 on my iPhone 12 Pro Max. Since upgrading to iOS 16.1 though, frequently when I tap on a mail notification in the Lock Screen, mail opens and just hangs there unresponsive for 5 seconds or so before I can interact with it. I doesn’t go to the message I tapped. After that it’s okay as long as I don’t open a bunch of other apps. It I do it hangs again.
