I've only recently started using Garmin Express for syncing and updates.
I've just noticed an issue that only happens when syncing my device using Garmin Express where recent activities are wiped from the device.
For example, this week, I've Swam (Monday, Ran (Tuesday), Swam (Wednesday) and Strength workout today. prior to syncing, I could see the current weeks activities, along with duration and type via the History widget (set to current week)
Syncing via Connect mobile works fine and doesn't wipe any history.
Strange that the workouts left on the device are from Feb, then back to August
History shows an activity count of 57 after syncing via Garmin Express using USB, prior to this there were 300+
Does anyone else notice this issue, I also tested this on using the same Garmin Express and my wifes Vivoactive 4S
