Happened to me as well. Lost 1.5 hours of a 3 hour ride.
In addition to saving that “lost” data, how do you recover and pick up where you left off if you are doing a workout? I know I can restart the workout and skip through the different blocks, but I was in the middle of a 1 hour steady block. I know that’s not the end of the world, just ride…But I had the whole thing set up as a workout in erg mode. At best, I have to redo 30 minutes or lose 30 minutes if I want to continue that particular workout. Is there no way to fast forward to a specific time?
Also, if erg mode drops out (if you stop peddling and forget to hit pause, it will shut down erg mode), is there anyway to reactive erg mode without restarting. These little things have bitten me pretty hard in recent workouts
