Hi @ Byrese! Not a big fan of Cortana, but it is really a neat and amazing W10 feature. I'm sure you have been to settings and checked things.
Here's a neat link from HTG that might help you get better acquainted with Cortana. Thought I would answer your question. I like to see everyone's question answered.
I spend way to much time here on WC forum!:smile: How to Use and Configure Cortana on Windows 10
So I just got my first traffic notification in ages. But I think its because I now (again) have W10M. Using my Note 5 perhaps the Cortana settings didn't properly align.
Or the settings (driving/transit, etc.) have to be the same on both devices.
