Hello, on June 24, the Sleep Timeline on my Fitbit app showed a low value for Deep Sleep. Surprisingly, on June 25, the Sleep Timeline Deep Sleep for June 24 was changed to 1h 32m (and the corresponding graph changed). In fact, the Deep Sleep in the Timeline for June 25 was uncharacteristically high (2h 14m). I lost confidence in the sleep data since June 24.
On June 25, I found the sleep.json file, which contains the data for June 24: It sill shows the >original< June 24 data for Deep Sleep. However, the UserSleepStages csv file shows the >new< June 24 data (1h 32m) for Deep Sleep.
On June 27, I called the 1-800 number and was directed to change the Sleep Tracking to Sensitive; however, the UserSleepStages CSV data for Jun 28 still is different from the Sleep JSON data. It looks like the two files are using different algorithms to determine the sleep stages.
Please help!
