Amazfit workout / activities maps data missing
Mi Band 4 / Amazfit GTR / Amazfit GTS / Amazfit Verge
When official app is installed, you can sync workout data only one time, then data get deleted by watch!
If some data has not been synced correctly from band (or is missing), you can re-sync old data from the band
Ensure you can see the old workout on the band activities history list, or data cannot be synced (missing from band)
