Farcical. Absolute shell of the app it used to be. Doesn't work properly on a Samsung Galaxy Watch 4 - the GPS won't work whatsoever. All previous challenges completed throughout the past years have now been deleted - very disappointing. My last manually logged workout hasn't even synced after almost an hour (the only reason I still manually log data is I had already started "You versus the Year" challenge and I wanted to complete it). So glad I moved to Strava which is superior in every way.
