Fitbit Sense has not shown a resting HR for over a week, but does track HR.

My fitibt Sense is having trouble with my resting heart rate. I don't know if it's the device, the app, or my Samsung S21. Everything has been deleted, reset, re-installed and restarted.

I do get current Heart rate on my Sense when I look at it and during exercise  it seems pretty accurate.

I do think my heart rhythm is a little irregular as I have had past episodes of PAC's (premature atrial contractions) which they said were not a problem. I'm pretty sure I've been having them again and I think it makes my heart rate harder to count. When I got tested they told me that they go away when my heart rate is higher because it doesn't have time for the little extra beat. 

Even with my PAC's I'm surprised it hasn't shown ANY resting heart rate since 2/23. My cardiologist didn't agree with me that it's related to my exercise, but I swear it happened last time when  I had begun more intense cardio (higher intensity zumba) and my resting rate got lower. During covid it went away because I was doing zumba lower intensity at home. Now it's back and I've recently upped my cardio again.

Is the problem with my Heart rate being to hard to read or with my device? I'd think I'd get SOME number...

ALSO, I signed up for my 6 month free PREMIUM trial, which is useless when I can't get a RHR or Sleep info. (sleep isn't working either)

I believe if you are having arrhythmias it will be difficult for the watch to get an accurate, resting heart rate. When you've felt these episodes, have you tried actually doing the ECG with the sense? That would be interesting if it's able to pick that up.
