A few days ago, I lost hours of work because I didn't realize that Evernote wasn't saving any changes that I was making to my notes. Since then, Evernote hasn't saved anything. I've tried logging out and back in, uninstalling Evernote from my computer and re-installing, but nothing works. I can log in and I see all my notes. I can even write on the notes but the moment I click away, all of the changes I've made are gone. This happened very suddenly a few days ago and it hasn't worked since then. I'm using the Windows program. On my phone, everything still works as normal.
