Location feature broken – Wahoo RunFit Review

Was going to do a max heart rate test. The app told me to enable it in Location Services in the Privacy tab of the Settings app. But when I went to do that, RunFit doesn't show up under Location Services so that I can give it permission to use my location. Therefore, it won't let me do a max heart rate test. Please fix this, Wahoo.
