my reply above did not fully work. notes app, as in another thread, reset within airplane mode, and outside of it.
I saw that if i unsync from cloud, there is a warning that it will delete notes from the device. i don't know if that is true. Some articles say it will not be deleted, and others say the opposite.
It is possible some notes were created on an old device, but I really don't know about that, or if so, how many.
Cloud storage for notes seems to say 0kb.
-notes also shows the note that was created on the device (and is stored there), will show it there sometimes in airplane mode, and sometimes not. Then the search feature sometimes turns off in both modes.
-it then will also not show the notes probably at all sometimes when the internet is disconnected.
i do not know if this a cloud issue or not. Since it will sometimes allow the search function in airplane mode, but also the feature says "there aren't any notes" sometimes when the internet is disconnected (something like that), then it means some kind of programming is telling the phone there isn't any notes, even though they are stored on the phone.
