Watch Sleep tracking not accurate or missing, missing nap tracking

I too am extremely dissatified with sleep tracking support. There are 2 things: 1. I and many older adults get up during the night to go to the bathroom. More days than not, I get NO sleep data. And when i do, it is incorrect 100% of the time. This is unacceptable and your explanations (excuses?) don't hold water. How do i know? I've taken to also wearing my old fitbit and am getting accurate readings every time. Even naps, of which i take plenty, once i got older and developed heart issues. Unless, your target audience is the young and healty, you need to accept this as a real issue and fix it. Because of my heart issue, i must get enough quality sleep. (Hence the naps) i love my watch, but if you can't fix it, i will have to find another solution. 2. Lastly, (again because of the heart issue), I need a way to accurately track my heart rate. Particully, during exercise, the number is sometimes funky. In the gym, a machine might register for example 110 and the watch will jump to 250. I would have to take it off for a bit to let it reset. The first few times it terrified me. Now, I ignore. Not a good thing for a heart patient.
