Weekly Intensity Minutes setting resetting

Do have this issue, too (Forerunner 255 music).

I'll try to use automatic detection instead of using HR-Zones...we'll see

Thanks Venacephalica.  I haven't had good results with the automatic detection--it gives me intensity minutes even if my HR is below Zone 1, which is why I wanted to set the zones manually.

 I use an Iphone with IOS 16 public beta, perhaps this could be the problem?

Activity Tracking>Weekly Intensity Minutes>Use Heart Rate Zones to ON and set my Moderate and Vigorous zones to 2 and 3.

Where do you do that? I have troubles with my intensity levels. I switched from FR645m to FR955, and with the same running load, I have barely 50 minutes registered a week, while it was on FR645 over 300 minutes

Looks like they changed the menu structure.  In the Garmin Connect mobile app:  Click on your device to open the device settings.  Then select Health & Wellness, then Weekly Intensity Minutes.  Turn on "Use Heart Rate Zones" and select the desired zones for Moderate Intensity and Vigorous Intensity.  I choose Zone 2 for moderate and Zone 3 for vigorous and it works pretty well for me.

Thx, found it. Settings are OK though. Heartratezones on. Moderate = zone 3, Vigorous=zone 4. But it has dropped a lot since I changed from 645 to 955. last 6 weeks: 492/497/527/632/131/160.

Guess when I changed my watch :-). I almost think connect app used other zones when I used my previous watch.

EDIT: the manual says it normally has to be zone 2 and 3 instead of 3 and 4. That is probably my issue. When setting up the FR955, I might have changed this setting, not knowing what to do :-)
