i still cant get used to it, and i'm someone who is very very "tolerant" of Apple. As i have an iPhone 6, i now have to first unlock the phone, then go into NC to view notifications. As this unlocking procedure has crashed the phone at least 20 times, until hopefully Beta2 sorts this out, i've resorted to disabling my passcode. This has had two benefits, 1.The phone doesn't crash
2. when a notification comes, i just tap it (good old ios10 behaviour) and i go straight to it.
i know of course that in ios10 after you tapped a notification you still had to unlock the phone, but when you did this you went straight to the application concerned. i cant for the life of me understand why Apple thought this was wrong and changed it
