When I want to write a note, Logos suggests 5 possible notebooks. I have downloaded a lot of public notebooks. Often Logos will suggest those notebooks to me, even though I cannot add a note to them.
This note looks like I can add a note, even though all the previous notes are locked. But a popup appeared telling me that if I put a note here, it would go to ALL notes, because this notebook is read-only.
Sometimes all five suggested notebooks are like that.
