I don't remember exactly when notes don't be saved, but I keep a lot of attention saving (hitting always "Save") and sometimes note don't save. But one thing I can say with certainty: also notes already saved sometimes disappear partially, as if the kobo load an earlier save. Here's an example: suppose I have written 5 lines of text in the note. I save, all it's okay. Then I decide to change what is written, adding a few lines of text. At this point it may happen that, after saving, I find myself with a note of half a line, losing all the text!
