This has happened a couple of times now:
What I did: Used “Send by Email” from the menu to send a note
What happened: Some part of the note were not copied over into the email. Sometimes it’s the last word of the first heading; this most recent time it was the last word of the note.
What I expected: That the whole note would be copied
Things that might be helpful to know (Agenda version, OS and model, etc):
I’m on an iMac, OS 10.15.7
