I have had my Versa 2 since may. I do CrossFit and I use it to keep track of my burnt calories. Then a couple days ago my heart rate sensor stopped working while I was working out. It read my heart rate was at 75 BPM when It was clearly much higher than that. I currently don't have it on my wrist and the light is not flashing and it reads that my heart rate is at 97 BPM when it clearly isn't. Also, it decided to do a hard reset twice in the middle of my workout today. This was my favorite smart watch, but after this I may have to switch over to Garmin. I have read all the troubleshooting techniques. I have switched bands, changed the placement on my wrist, whipped it down with alcohol, did a hard reset everyday, even reset it back to factory settings. I don't know what else to do but look at what other options I might have.
