Can't update max heart rate

I'm trying to update my max heart rate and am following these instructions, but when I go to the user profile, I do not see "Heart Rate and Power Zones." Any thoughts on where that might be? Steps in the Garmin Connect mobile app
Open the Garmin Connect app and sign in.

Select your device from the device list.

Go to More (menu) → Garmin Devices → your device name.

Tap User Profile → Heart Rate & Power Zones → Heart Rate → Zones


Edit your zones or let Garmin auto-detect them based on your max heart rate


Save changes — they will sync to your device when you connect it.
