Given that the ability of my Runner 3 to sync with my phone (and, from there, the website) has deteriorated from 100% in May, when I bought it, to pretty much zero in recent weeks, I'm wondering whether it would be possible to use the watch without bothering with the app at all. Will the watch automatically sync with Tomtom Sports (and from there, Strava etc.) if I connect it to my computer and start Tomtom Sports Connect?
I honestly wouldn't miss the app at all; it looks as though it was designed for ten-year-olds, routinely crashes when I open it, and no longer manages to sync in any case. Uninstalling it would be no loss at this rate.
