All of these features from SmartNote 22 seem to be missing or functioning incorrectly in SmartNote 23. I recently opened a ticket about this and was recommended to post here about these features either being implemented into 23 or otherwise. At this point I've told my campus' teachers to just open things in SmartNote 22 instead of 23 due to the missing features.

To be specific, Dual View and pinning are not present as others have mentioned. The Screen recording whether used through SmartNote or in the settings function both operate oddly. They will give partial screens even when the entire one is selected as well as very distorted video.
