Garmin Running Power on the 5S

Per DCRainmaker https://www.dcrainmaker.com/2017/12/garmin-running-power-good.html, the fenix5 (& I would imagine the 5s) should be able to show running power if I have the Tri-HRM (which I do). Did a test around my block and although I can see power on my watch while I was running, it doesn't show up on Garmin Connect :(.
