Ever since #WatchOS v10, my heart rate tracking has been mostly broken when I use the fitness app to track a bike ride.
Start the ride, heart rate jumps to double. Stop, it goes back. Start riding again and after 10 minutes, heart rate jumps by 50%, then the heart rate monitor crashes/resets and after 2 minutes, it comes back to normal.
This cycle usually repeats itself 1 more time. #biketooter
