What I did: I created a new note on my iPad (same on iPhone). I gave it a title, pressed return which resulted in the cursor position in the body of the note. Then I pasted some text (tried both a single line and multiple lines as well.)
What happened: the text got pasted but the cursor remained at the insertion point (at the beginning of the note in this case). I had to position it to the end of the pasted text manually.
What I expected: the cursor at the end of the pasted text, like in Apple Notes, Bear, etc. so that I can continue typing after the pasted text.
Things that might be helpful to know (Agenda version, OS and model, etc): 9.1.2 (latest App Store version, iOS/iPadOS 13.3)
