I was thinking about posting that this issue appears to be resolved and dead because I had not experienced it for several weeks. Unfortunately this was wishful thinking. It is back on my iPhone 5 and now I have about half a dozen unsynced notes. All photos. The bottleneck is a note with only 5 attached photos. I am not a tech guy, but it seems like the issue here is a configuration or setting on the Evernote end that needs to be tweaked. How can it be so complex/difficult? This is fast turning my favorite app into my most frustrating.
