failed sync with evernote web leads to data loss!

[tch 1]

I am a paid customer and long term user of Evernote web in Ubuntu chrome browser. Today I wrote on an existing note, when I clicked into another note and switched back I found all my edits were not recorded/uploaded. They are entirely gone, not even in the note history! It is a painful experience and I have to spent hours to recreate the note. I hope Evernote team could continue improve their web version, especially to add features like notifying users whether or not current edit has been synced, just as the desktop version, or Google doc, would do..
