For the first time since owning my TomTom Runner 3 cardio (a couple of years now) I:ve experienced a syncing problem. I did an activity this morning that did not upload via the mobile app. I managed to find the .ttbin file on my phone and have copied it across to my PC. I have read online that the correct way to manually upload it is to open TomTom Sports Connect, connect my watch to the PC and then double click on the .ttbin file. When I double click, nothing happens - sometimes it will switch window to Sports Connect, but the program will not actually do anything; it just says "Ready to go - charging".
Is there another way to get the ttbin file sent to TomTom and my other sports apps (Strava and Runkeeper)?
Many thanks in advance.
