Hi there! I just got my Fitbit Sense 5 days ago, and the sleeping heart rate graph is blank, but the data is there. I have the iPhone XR and I have the newest iOS and Fitbit software. I have tried deleting the App and re-installing it and nothing seems to work. Is there a way to fix this? Thanks!
Best AnswerThere are a couple threads out there. This is a known problem and Fitbit is working on it.
