I use the smaller iPad Pro with the Apple pencil to take notes - primarily in portrait mode. If the screen gets rotated to landscape for any reason, the text view scales up correctly to take up the available space. However, the same is not true when rotating back. To get the text to fit portrait mode again, I have to back out of the note using (<) to the screen showing all notes in the notebook.. This is very annoying and makes the application very difficult to use especially in for dynamic notes. Locking the rotation is not a suitable solution as I also use a keyboard for other apps (landscape mode).
Known issue? User error?
