Thanks for the advice @Kaigogi.
Good to know you solved the problem and how. It would be very bad to lose the activity that has not been synced yet. I'll wait to see if we can get an answer and use...
Hello Jess, thanks for the answers above. Good to know that someone is looking for us ;)
I experience the same problem reported by Kaigogi M:
1. I open Strava app in my watch
2. Click "History"
Strava team, please consider supporting Xiami Mi Band 2. Thanks.
