Can someone please explain how 'Available slots' on the VA3 (as reported by the Connect app on my phone) equates to events I can store on the device? I've had it twice now where only the last 8 events were retained from gym sessions and made it onto Garmin Connect, and a number were lost (probably 4 or 5 strength events and a cardio event). I can only assume it is overwriting the earlier events going off the timestamps of what is there. I do not carry my phone around in the gym and sync before I start and again when I finish, but I would've hoped it would be able to store a dozen or so events without the need to sync. The HR data for when the missing events happened is definitely there and MoveIQ even correctly guesses what I was doing. Although you don't appear to be able to change a MoveIQ event to an activity event.
I did have a couple of watch faces installed and this left me with 13 slots available and have since cleared some off and its upped to 15 (775K). So I wasn't quite sure how capacity for events and slots available correlates.
