I just upgraded my Windows desktop client to v220.127.116.1121 (306921) Public (CE Build ce-1.39.4387)...and now all my notes have disappeared! Just like the others have reported, I can see the notes in the Note Panel, but the body of the note is blank. All the notes appear on the web interface as well. I tried the workaround suggested above by changing to presentation mode and that shows the text, but certainly not ideal. I have logged out and back in, synced the data...still no resolve. Reinstalled v6.7.5...all notes restored.
