The first few weeks after I got my fitbit sense the EDA scan worked as expected and normally detected a HRV. Lately it never detects hearth rate variability, though it detects hearth rate and EDA responses. Since it almost always worked for the first few weeks, and never for the last months, I am pretty sure it is a hardwear or softwear issue and not user error. I have updated the fitbit app on my phone and restarted both sense and phone multiple times. I also keep completely still during EDA scans and have tried resting my arm on both hard and soft surfaces. The HRV measurements during sleep work as it should. How do I solve this?
