Had this Sense 2 for about a year. Had the Irregular Rhythm monitor on and everything worked for the most part until July 8th, when the Fitbit detected an Irregular Rhythm. Had AFib confirmed by the Doctor and am being treated accordingly. On that day, the HRV, BR and Sleep Stages all stopped working and haven’t worked since. I read somewhere on the community that using the IR monitoring can affect recording of these elements so switched it off. This had no effect. Have tried all the reinstalls, resets etc, but still nothing. This morning I don’t even have sleep duration or resting heart rate. All I have now is a cheap watch!! Believe either the Fitbit is defective or the app.
