Seems to happen in any project. At first I thought it was because I attempted to turn the phone to landscape mode… but then it happened again in portrait.
Really puzzled by it, since I can’t seem to find the steps that create the problem.
The note does return if I navigate to a different project and then come back.
In a project with more than 4 notes, try creating a new one and then turning the phone to landscape. The newest note (the one you’ve just created) vanishes.
I frequently find that a newly-created note seems to be missing, because it’s created at the top of the list, and Agenda doesn’t scroll to it. So, I have to scroll to the top to reveal the note.
I think I’ve seen it on both. I’m not exactly sure what the conditions are. I think it’s when I create a note with a date that puts it above the notes I’m currently looking at. I’ll pay more attention the next time it happens and report here.
