The other thread was closed but the problem persists.After more than 7 days and the sleep index monitor still does not generate a Body Battery value. Only after I put on my Fenix 6X in the morning a number is shown (but the night remains blank). However, stress and HRV and sleep are well recorded by the monitor during the night. The workaround proposed by Garmin (see below) does not work.
If this will not be resolved I due course I will send the monitor back because it just doesn't work as advertised.
Please fix it Garmin.

Hello!
We have made improvements to this interaction in the 12.70 software update for users who have fenix 8 Series, Forerunner 570/970, Vivoactive 6, and Venu X1.
Users who have an older device may need to use the following workaround to eliminate the possibility of false on-wrist detection by their paired wearable.
Ensure Garmin Connect mobile app is open and running on the phone.
Verify the watch synced in the last 5 minutes. You may need to go to More > Garmin Devices > Device Name to manually sync.
Put on Index Sleep Monitor and verify that it vibrates indicating it has connected and is recording heart rate.
Remove watch from their wrist and power off.
Go to sleep.
Upon waking, remove ISM and turn it inside out, OHR facing up.
Verify that the Index Sleep Monitor is syncing to the Garmin Connect mobile app.
Power on watch and put on wrist.
Verify that watch syncs. The 2 devices may need to sync multiple times for a full True Up of all data.
If you experience this issue after updating your watch to 12.70 please create a new thread.
