Marshmallow 6.0.1 - GPS Worthless

I have an AT&T Note 5 running via Straight Talk, and guess I should have left well enough alone, but since it took AT&T forever to release 6.0.1 for this phone, I decided to take the plunge. I used my my phones GPS everyday, if I'm not walking for exercise, then I'm running, riding, or using Google Maps to navigate. Before my Update on Saturday (25th), all apps, and Maps worked flawlessly. Now if I can get GPS signal, its good for 50' - 100', and then gone, it might come back in 15 - 20 minutes, by then you are miles away.
I'm not sure how GPS hardware talks through Android, but something after the update did not go right. :(
