I find these 'Nice Jump!' notifications to be annoying and excessive. I think the mountain bike metrics are cool and don't mind having them available to review post-ride, but the persistent beeping can get old on sections where they basically go off non stop.
The only way around this I've found is to change the activity type to something other than 'Mountain Bike' in the Activity Profile. The annoyance with this for me is that my mountain bike rides sync to TrainingPeaks as road bike rides and I have to go in and manually change them.
Does anyone know if it's possible to disable the notifications?
