Haven’t used my One really since buying. I did use it on some tracking jumps last week (Squirrel Mutation) on Skydiving mode and it correctly registered the tracking times (1:50 to 2:00) but on Wingsuit mode, it registered over 4 minutes.
I would have thought it should be on Wingsuit mode for tracking but let me know if not. Also to add, I switched it back to skydive mode so don’t have comprehensive proof it’s an issue or a one off! Would be good to know though.
