Watch paired to chest strap but still using wrist sensor?

So my Forerunner 945 LTE is paired with my HRM Pro chest strap. My understanding is that the watch should now be using the chest stram HR data and not the wrist-sensor HR data (as long as my chest strap is actually on, which it is as I write this). However, I still see those green LEDS going at the back of the watch. Also, when I take the watch off my wrist, it stops showing heart rate even though I'm wearing my HRM Pro and the watch is showing the HRM Pro as connected.

When you say the strap is "on", are you looking in sensors and seeing that it's paired and connected? It will only use HR from the strap if an activity is started.

Yes, showing as paired and connected in sensors. However, saw the green lights during activity as well. Have you checked this and found they go off during an activity if the watch is paired to an extern HR sensor?

Most of the time. If you use Garmin Pay and input your security code the lights stay on as a security function. This way if the watch is removed, the wrist sensor detects it and locks Garmin Pay until your security code is entered again. Is this something you might be experiencing?

Nope, not using Garmin Pay or any other similar non-sports-related "smart watch" functionality (music, messages, etc - none of it).
