I have noticed this week that the last word entered in a note has been deleted when going back in to the note. This can be a whole word or a single standalone alpha, numeric or special character.
Having experimented today, if you add a carriage return then the last part of the entry is saved. This was never the case.
I have uninstalled the app and reinstalled but that hasn't sorted it. It is very annoying and is a problem solely with the mobile app for Samsung and not the desktop for Windows.
