iOS Garmin Connect Body Battery not syncing. Instinct 3 Solar.

I have a Garmin 3 Solar 50 mm. I can see body battery on my watch but it will not sync to Garmin Connect. It is a new watch (3 weeks old) and it has never synced. Everything else syncs fine. I see sleep, pulse ox, activities, stress, but no body battery. I asked Chat GPT. It says that my iPhone 16 has a motion and fitness permission in the iOS that needs to have Garmin Connect listed, but I don't see it. I have unpaired and re-paired the device. I uninstalled Garmin Connect and reinstalled. Nothing is working. Any advice?
