There may be an issue with the Strava push API, if it fails, we fall back on checking your account once a day for any new activities. Investigating now.
Still not working for my strava sync. 3 from this weekend, not showing, and oddly, 1 out of 4 from a week in Feb doesn't show on TF.
Looking into it now, added some debugging to monitor. I can see in our logs that your activities were added to the import queue but failed 3 times. Not sure why at this point.
Auto-import from Strava didn't record my last mountain bike ride... it also happened to be my first ride recorded with my Lezyne GPS device which auto updates Strava... but then it seems Strava didn't update Trailforks? I had to go in and manually force it to update.
