I found that the heart rate value displayed is not same as Samsung watch hear rate. E.g. Samsung watch is 90 but your watch face show 79. And stay in 79 for a 10 or more minutes before change to another heart rate value. Or need to click heart icon a few time to make it refresh It seem.not refresh enough to show correct real time heart rate value. Is that a bug ? Do you have solution for that as real time heart rate is important to me. Other than realtime heart rate issue the watch face good
