It seems like some historical data for my steps have been missmigrated?
What I have been notified today with was:
40K Step Badge
50K Step Badge
200 Intensity Minutes Badge
300 Intensity Minutes Badge
All of them apparently have been added for a day in the past, where my steps started to be counted in the middle of the night.
All other activities match (sleep, running, Yoga), so it seems like I have received data from someone else, in the deep past.
Please do repair, I would like to achieve these myself!
