Thanks for the reply. I'm referring to my old notes app that came with my phone, not the old version of evernote. This is my first time using evernote, so I don't have old accounts. I do have different email addresses that I tried synching it with a few times to see if I'd get a different response, but then I end up with no notes. My main, and most common email address is the only one that shows any notes at all.
I recently upgraded my HTC One to 5.0.2, and my old notes app no longer opens as it is outdated. So when I clicked on it, it told me that I had to upgrade to evernote...and so I did. Only now, more than half of my notes are gone! A lot of important ones too, it synched a lot if old ones from a year or two ago that I barely even care for. Please tell me the there is a way to recover ALL of my notes...especially some of the more recent ones!? Thanks.
