I have identified the cause of the issue.
The “race s” device resets the step count every midnight. The issue seems to occur when the power is turned off before midnight and turned back on in the morning.
When the device is powered on in the morning, the time is reset, and as a result, today’s step count is not processed correctly.
I have confirmed that this issue does not occur if the device is turned off after midnight and turned back on in the morning.
This issue appears to require a fix.
