I am not clear on what is causing the crash, but for the past 3 days I have woke up with the watch passcode screen visible and no morning report is being generate. I can only assume the watch is crashing/restarting (causing the passcode lock to be visible) when it tries to create the morning report. I have Pulse O2 enabled during sleep and all activities being generated/selected in the morning report if this is helpful to reproduce the issue. If I can provide a diag log or other debugging info, please let me know.
