Hi, @ro_kamath , sometimes phones are a bit “laggy” in updating the app. Also it often takes a few moments for sleep to be updated. I know I often don’t get my latest day sleep score immediately after I get up. Maybe they really want to make sure your sleep has ended. It is possible that the brief delay is deliberately built in, but in any case it is something I have often noted over the years I have been tracking my sleep with Fitbit.
