I have been using Garmin Venu 2s since May 2023 and I turned on power saving mode before going to sleep. Until the recent update, it was recording my heart rate and tracking sleep just fine in power saving mode, but now it does not anymore. Is there anything that can be done to fix this? I don't want my battery to drain so fast. I have already tried to restart the watch by pressing the turn off button for 30 seconds many times now. Thanks for the help.
