I can’t see the REM Sleep hours in the Sleep Analysis of my Watch Lite SE.

The new REM Sleep analysis requires the 24h monitoring feature to be on. When activated, the 24h monitoring feature will take six (6) hours to effectively begin monitoring, as the watch will monitor and collect atrial activity to establish baseline parameters.

Please note: The REM Sleep service is only available if you have an active monthly subscription.
