The band syncs correctly to the app. The correct number of steps show in the activity area but, the weekly chart does not reflect the same number of steps. My husband has the same issue. I have a Pixel 4 and he has a Pixel 3a.
I haven’t seen this issue elsewhere but, it is very frustrating. Since the sync goes through the daily activity is correct but, on the weekly chart there is a lower number of steps. I have submitted a few tickets with screenshots from both phones.
Sometimes the difference is minimal but, today I lost a few thousand steps and yesterday my husband lost 10,000.
Anyone else having this trouble? Thanks!
