Before update to 12.70, " Heart Rate Alert" works. 

After updates to 17.70, for some other issues, i did soft and hard reset, factory reset. " Heart Rate Alert" fails to work. 

I did following settings:

Sound & Vibe - Alert Tones - On

Sound & Vibe - Volume - Mute All - Off

Sound & Vibe - Voice - 50%

Sound & Vibe - system - 50%

Focus Modes - Activity - Voice Alerts - 

Audio Output   - Watch

Heart Rate Alert - Status - On

Heart Rate Alert - Alert Type - Heart Rate

Alert Frequency - 1 min.  (It does not work. There is no heart rate every 1 minute)

Time Events On ( There is event start and stop sound. This works!).

Activities - Run - Audio Output - Watch

Activities - Run - Metronome - On (it works, I could hear the metronome sound).

Activities - Run - Alerts - Heart Rate - Hight Heart Rate / Low heart Rate (It works. It has the heart rate sound if it is too low or too high).

I wish to hear the hear rate number every one minute so that I do not need to look at the watch. 

Could any one help me how to adjust the settings? Is it a bug in 12.70 ?

Thank you!
