Since the proper function of the Charge 4 (and other devices) depends greatly on whether the sensors facing the skin are able to get accurate readings, I would think that Fitbit would provide the wearer some information as to their status.
For example if the O2 sensor couldn't get a good reading because the wriststrap was too loose, the device should inform the user. And no, I'm not getting any EOV reports.
Seems like an easy feature to provide.
