Average speed in hundredths

Hi Guys,
A friend of mine has the Strava app, and for her the average speed is displayed in hundredths, whereas for me, it’s in tenths. We are both free users, and haven’t been able to find anything where this can be set. I would very much like to have the speed in hundredths too, if possible. Is there a way of setting this?
My second question is that right now, it’s showing live speed instead of average. I’ve read that this is because the free subscription preview is active. Is there any way to end the preview early, so that I can get average speed back?
Thanks, Harry
