Ascent and descent totals during Mountain Bike Activity

I have only had the 830 for a week previously using a Fenix 5 and during any cycling activity I could view the accumulated ascent and descent during the ride.. I cannot see that on the 830 during a mountain bike activity. Only shows current elevation. Can anyone learn me on this? Of course once ride is over the totals are available but would like to view during the ride. Thanks in advance, Johnny
