I slept more than an hour and 46 minutes from last night until the hour 46 minutes identified.
My Versa 2 has missed an entire day of data (i.e. sleep) and no SpO² missing again, day 3 of no sleep data. Oct. 31 sleep data is there (6 hrs plus) but NO data for Nov. 1. This is a random occurrence as far as sleep data and a continuous occurrence when it comes to O² data from SpO². My battery is at 53%.
