Estimated Oxygen Variation

Hi, I have had a Fitbit Inspire Hr for a couple months now it works with my new apple phone well. Only sometimes this estimated oxygen  feature will pop up under my sleep stages.. but it never has any thing actually in the chart, it is just empty? Can anyone please tell me why this is?

Hello @Jade003 and a warm welcome.  The Inspire HR doesn't have the hardware to measure the SpO2 that is used in the Estimated Oxygen Variation.  Only Ionic, Versa family and Charge 3 users can get the graph.  Everyone else gets a blank graph.
