What I did: I used the app in my IPhone and Mac.
What happened: The option to move notes to different projects has disappeared from IPhone App
What I expected: For it to work like it did before.

On iPhone the actions from the gear menu have moved into the menu that you get when pressing the orange dot next to the title. This to save valuable vertical space on the small screen.
Btw an alternative is to drag the note to the left edge upon which the sidebar should show and you can drag the note in the relevant project to move it.
