All my notes are GONE! Help??

I logged out yesterday, logged back in today. My notebooks and notes are completely empty. "Record notes to preserve your thoughts" Oh dear. Are they just hiding somewhere? This is serious. This is my journal. No backup. :O
Any help would be greatly appreciated.

There are some issues with annotations and notes and they have been temporarily disabled in the web interface.

See if it is working for you now.

Yes, they're back. Thanks so much.
