Time in heart rate zones not registering

I have recently purchased a garmin swim 2 which I'm using with the android garmin connect app. I seem to have the heart rate zones set up ok, I'm 49 and when I check the garmin connect app I can see the heart rate zones are based on "% of max".

Max Heart rate: 171 100%

Zone 1: 86 BPM 50% to 103 BPM 60%

Zone 2: 103 BPM 60% to 120 BPM 70%

Zone 3: 120 BPM 70% to 137 BPM 80%

Zone 4: 137 BPM 80% to 154 BPM 90%

Zone 5: 154 BPM 90% to 171 BPM 100%

When I check the data related to a steady 39 minute lap swim I see average heart rate for the activity was 154 BPM, max heart rate 165 BPM.

However when I check the time spent in each of the 5 heart rates zones on the gamin connet app it shows zero for all zones? Can anybody advise why this is the case and what settings I need to change to shown the correct amount of time for the session in each heart rate zone?

Any help much appreciated.

@Scirish Swimmer, my swim 2 is now logging times in each of the 5 heart rate zones. It seemed to start working ok after I manually entered the min and max BPM for each of the heart rate zones.

The data I manually entered was identical to the default data based on my age, sex, weight etc.

@8541377 thanks for that. I’ll give it a try.

How were you able to do this? With the latest Connect Mobile iOS is practically impossible to enter the heart rate values, whatever I try. At least on my iPhone 11 with iOS 13.3.1.

I just manually overwrote the existing numbers with figures that were slightly different and it seems to work now.

Thanks for your reply. At the beginning I couldn't enter anything in half of the fields because the pickers had no values. After entering the values in Garmin Express on the Mac, changing them a few times in Garmin Connect (in the browser) and synching a few times between the desktop, the device and the iPhone, everything seems to be ok. I can now edit the values without issues also in the mobile application. Probably an initialization issue in the mobile app.

I am having this problem as well. Tried suggestion of manually entering slightly different BPM in Garmin Connect and no success as of yet. Will try with my mac and Garmin Connect App as one person suggested and see if that works.

I just received my Garmin Swim 2 and have the same problem and the hacks didn't work! Garmin should have fixed this software problem after a year :(

I'm also in this boat. I adjusted the HR zones manually, and now they show up for my swims, but not for any of the other workouts I track. It's a bit frustrating that I'm not getting these stats considering the price of the Swim 2, when my husband's $30 Mi Band can do this.... I hope Garmin fixes this soon!!

I have the same issue. I configure the HR zones manually, and now it's working for swimming, but not for cardio workouts. Can Garmin solve this problem with an update?
