Is it possible to open MTB dynamics during a recording? I somehow was able to, but I'm not able to reproduce it.
Thanis
No there is Garmin provided jump count info accessible during the ride, but someone may have written a Connect IQ app/data field that shows it.
If you have "Fork Sight" enabled and it is showing something, you can swipe to the left to see the jumps, but I don't know how to trigger fork sight manually.
