Something Bad Happened & has been going on long enough it should have been fixed by now. Glitch, Glitch, Freeze, Delete parts, duplicate others, can not complete without closing & re-opening, then fix all app errors. I understand errors occur & rarely comment on them as they get fixed in an update or two. This issue has had enough awareness & time to be corrected. Feels like, as with other things, Samsung may be giving up on Notes App. Too bad it was great.
