Me too. I opened Evernote on my iPhone yesterday after not having used it on that device for quite a while. I didn't even change anything, just viewed one note. Now, today, I open Evernote on my desktop which I use, and sync, everyday and realized at least one of my notes is very old and I didn't even open this note on my iPhone. Who knows what other notes have also been affected.
It used to be that I would get sync errors and had to manual resolve them. Now, it just overwrites my data. Horrible!
