If your sleep data is missing it means that Eight did not record any sleep data from the last night. This could simply mean that you were away for the evening, or perhaps your Eight has disconnected from Wi-Fi.
In the Last Night view, you will receive a message that you’re missing sleep data.
In the Trends view, nights without recorded sleep data will display a gray dot and line.
