Before the last update, it was possible to have, in a report, the total amount of kilometers made of all cycling activities, as sum of road bike, mtb, indoor cycling, etc. just using the generic "cycling" activity... Now it is not possible, so you can't have a report of all the kilometers made.
For me, the new update is not correct, because the generic cycling, is a class that comrends of the sub classes, indoor, mt,, road, etc...
