I recently changed my activity tracker, but although I factory reset my old device, I didn't remove it from my account. When I added the new device via Garmin Connect Mobile, I think there was pop-up on asking if I wanted to make it my default activity tracker, and I think I chose yes. But maybe I didn't, so I'm not making a bug report or so.
When I finally realised that something was going wrong, I removed the old device from https://my.garmin.com/mygarmin/customers/myUnits.htm and made sure that the activity tracking was turned on for my new device on https://connect.garmin.com . Now everything works and syncs fine, but the data from the previous days is ignored (which I perfectly understand...).
However, this data is still on the history of my new device. Is it possible to sync/upload it somehow?
PS: I have Physio True Up turned on.
