Save activity if Strava app is in out of service
In my opinion it would be great if Strava mobile app will allow to cache (save) an activity if it's in offline (no cellular network & wi-fi available). Now it's impossible to start a new activity if the current is still in action. But if Strava mobile app is offline it won't allow to save (finish) the activity and start a new one.
For some cases activitiy should be splitted up on several during one ride for example. Caching allows to finish as much activities as I want. When mobile app will be online I can upload them to Strava server.
