Ok, tried Settings, Apps, Evernote, Battery, and then there were 3 options: Unrestricted, Optimized or Restricted.
I was on Optimized, I moved to Unrestricted, and set a reminder for today. It still didn't come. Unfortunately it takes a day to check each change, as if I set a reminder for 2 hours from now, it works just fine, even with Optimized. It seems like it's the next day and beyond that don't remind other than the daily Email reminder. I had a support ticket open several months ago, and they had no idea, and "escalated" it after they had me play with it a while with different suggestions, but I never heard beyond after it was "escalated" and obviously, escalation didn't help! Oddly they gave me the impression they were unaware of this problem prior to my ticket.
