Do any of you guys saw a weird message "Transfer Completed" right after you click on the run button?
I am sure my watch is not connected to the phone or what so ever.
My assumption is that the watch is routinely syncing the other watch data--steps, RHR, VOMax, etc. and the toast is confirmation of that.Quite possibly, although just now I manually triggered a sync (with Garmin Connect Mobile running on my iPad), waited for it to complete (with the sync progress panel in the app at the bottom turning green, and then disappearing) and then thirty seconds more, then pressed at the watch face and – Presto! – the Transfer Complete ‘toast’ notification popped up immediately until getting into prepping for a Run. It makes me wonder whether the previous sync set a flag/bit on the watch upon completion, that doesn't get checked or actioned until the next time a screen in which toast notifications can be presented is brought up.
Apparently this is intended behaviour, so I've been told.
