I've noticed my Series 4 has been failing to register a Heart Rate consistently lately. It's getting frustrating, as I try to track workouts, and the HR section is greyed out.

I have reset the watch and I have cleaned the bottom. Is there anything else I can check? Or is there a tendency for the watch to burn out over time?

Aside from the monitor, things work fine (battery life, etc).
 
By any chance, did you get a tattoo on your wrist? That has been known to affect HR monitoring on the watch.
