I have recently switched to Venu 2 after cracking the screen of a Vivoactive 4. The sleep scores are disappointing. Even though I have slept well my sleep scores are low 40s and constantly less than an hour of deep sleep. It shows awake times when I know I haven't been awake. It looks like the Vivoactive was much more accurate with 1.5-3 hrs deep sleep mostly and accurate awake times. I wear a firm strap. Is this a known issue?
