Hi. I wore a vivosmart 4 for almost 3 years. It was a little banged up and I decided to upgrade to the vivosmart 5. My stress with the new device has spiked upwards, my resting hb is lower and I get intensity minutes for doing nothing. Why is there such a big and to me inaccurate difference with the new device? Can I level set it to what is normal for me? It is stressing me out to see my stress so high!!
