Since late this week, my activities keep on duplicating. The 2 rides I did yesterday were first 4 rides but are now 6 rides. What's going on? I have used this device for about a year, only started getting problematical this week, did you change anything?
Device is a Garmin Edge 520 Plus and I sync via my Android phone. Looks like every time I sync, I have more rides. Nice to 'earn' my badges and meet my challenges, not good really and completely unnecessary, IMO. Lots of people seems to have this issue, please fix this bug Garmin. How difficult is it to spot a duplicate, really!
