Charge 5 heart rate notifications not working

[TreasureTracker]

Hi, today I bought the Fitbit Charge 5 specifically for the heart rate alert. My doctor wants me to stop all activities, if my heart rate goes outside a certain range.

I tested it with my pulse oximeter and confirmed the heart rate meter was accurate, then set the alert accordingly. But while I was making dinner, the watch face showed I was well above range, yet the alert did not go off.

I've tested the countdown timer and it works (I assume it gives the same sort of alert)??

Any ideas on why I didn't get a heart rate alert??

Hi @TreasureTracker. It's good to see you here.

Thanks for the detailed information, and your efforts while working on this matter. I understand how important these heart rate notifications are for you and just to confirm, did you follow the steps described here to enable them? If that's correct, please give a try to the following steps and monitor your tracker's behavior in the next days:

1. Forget your Charge 5 from the Bluetooth settings.
2. Force quit the Fitbit app.
3. Restart your tracker to refresh its performance.
4. Make sure the Sleep Mode and DND settings are turned off. You'll find further instructions here.
5. Open the Fitbit app and pull down on the screen to force a manual sync.

Hope this helps.
