Apple iOS bugs continue w each new version. Need to fix sleep data that stopped working after downloading 13.5 on iPhone 10.
Please ensure your Golf APP and Connect APP are both fully updated through your Apple APP store. You can also try resetting your Approach S20 - How to Reset an Approach S20.
If you continue to have an issue with sleep metrics showing in Garmin Connect, please highlight my name and send me a Private Message. Thank you!
