I've had my sense for two and a half years in the last month tomonth and a half I've noticed the following. It has stopped tracking my sleep stages. It is also stopped being able to track my ECG, comes back inconclusive 95% of the time. Plus my heart rate compared to my blood pressure monitor is quite different. What is the life of the tracking sensors? I suspect it's about 2 years. Very disappointi gin a 300 watch. I have repeatedly done all the recommended fixes.
