I'm temporarily using a Series 3 while my Series 0 is away for battery service. I used both day before yesterday (paired simultaneously) and both gave me the same Longest Move Streak badge. Yesterday I unpaired my Series 0 and sent it to Apple. Later after meeting my Move goal, I was expecting another Longest Move Streak badge. But I didn't get one. When I looked in Fitness it showed the badge from the previous day (632 day) and said that the current Move streak was 629 days. This doesn't make any sense.
Yesterday, I found this thread (https://discussions.apple.com/thread/8079263) which contained a recommendation to restart both devices. I did that and then got a Longest Move Streak badge for 629 days.
Today it has gone back to displaying a Longest Move Streak badge for 632 days ending on 7 April 2021 and telling me that as of today (9 April 2021) I have a streak of 629 days):
This rather confusing.
