Good evening,
I have the same issue but on Windows, i followed the steps that PinkElephant posted but without any result.
Just for info I:
1. Unckecked "Keep data when leaving";
2. Logged out removing everything saved (no backup);
3. Quitted evernote;
4. Restarted the PC;
5. Logged in and waited the notes to sync;
6. Created a new note.
Is there any other metod i can try to fix?
Thanks in advance!
Kind regards,
Lorenzo
