How To Fix Cardio Fitness and Cardio Recovery Not Updating

After I got new iPhone 5 days ago, Cardio Fitness and Cardio Recovery stopped updating. Outdoor cardio workouts continued being captured.

After searching for suggestions, I tried all of restarting, resetting and unpairing and repairing Apple Watch. None of those helped.

Yesterday I found other suggestion to manually add data and then do workout with Apple Watch disconnected from iPhone by putting iPhone in airplane mode and turning off Bluetooth.

It seemed worth a try. This morning I manually added data for last four days and turned off Bluetooth before workout. I did not bother with airplane mode because did not seem necessary.

After workout, I turned on Bluetooth. Almost immediately not only did workout show in Fitness but also both Cardio Fitness and Cardio Recovery updated in Health with scores for today!

Maybe premature to claim total success at this point, but I’m betting both will continue updating as they used to without any manual intervention required. If not, I will reply otherwise.
