I'd like to report a bug. Since the new update, when time I merge a set of notes, it creates the new note, fully merged. Stays that way for about 3 seconds. Then it refreshes to show the newly merged note as blank, and all the merged notes are in the trash. I've just done this 3 times, restoring the notes each time, and seeing if I can workaround it by renaming the new note or not. No joy!
I'm going to do this manually by copy-paste, but it'd be great if you could commit to swiftly fix it.
