My Charge 5 does not show any breath rate. It has not for some time now. I have been helped by several people who have had very different approaches on how to remedy this. NONE OF THEM HAVE WORKED. The individuals have all been very polite, but nothing has worked. I have a premium account & attached myself to Google. I dislike all the changes , especially the sleep profile. There are just too many frustrations that appear with no resolution. Once this Charge 5 dies, I'm done with Fitbit!
