Linking two notes in iOS

What I did: Selected text within a note. Then hit + and the link symbol. Then tried to select another note to link.

What happened: Nothing.

What I expected: Linking the selected text (turning blue) to a note of my choosing.

Things that might be helpful to know (Agenda version, OS and model, etc): iPadOS 14.4.

Thanks for reporting, we have indeed fixed this issue in the 12.0.1 update that should be out later this week/early next week.
