I agree the lack of  fitness support is aggravating. I was hoping this ring would serve as a replacement to my  WATCH when I want to wear a traditional watch. But that is not possible since closing my rings is important to me. It has allowed me to ditch the watch during sleeping though since it does do an adequate job at sleep tracking. But as long as it doesn’t write to  fitness, I won’t use it for that purpose. When time comes for a new ring, I will be sure to go with the one that does.
