HR zones changed and I'm getting too many AZM

[dobbyM]

My Fitbit Charge 6 was working reasonably well until yesterday when it suddenly changed the limits for the various zones.

The moderate heart rate zone is now 91 to 92bpm, vigorous is 93 to 94bmp and peak is anything over 95 bpm.

Since I have a slightly higher heart rate, this change means that almost all minutes are now zone minutes and the watch constantly congratulates me for my achievements while I'm just sitting around doing nothing.

Maybe it's just a coincidence but just before all this started the app crashed a couple of times.

I have restarted the watch and I verified that I have the latest version of the app installed.

What may be the cause of this? How can I reset the activity zone limits? I'd like to solve it because I was mainly using the fitbit to track active minutes.

Yes.  All the data listed is accurate. Correct DOB…etc.

If your Fitbit account recently merged with a Google account, it could be worth checking the date of birth on your Google account as well.
