I am returning to this issue because it bothers me greatly. I keep monitored my sleep with a Holter because I am trying to investigate a problem that has been occurring for a couple of years (PVCs). There have been several fw updates, I have sent several logs, but I keep seeing graphs that are completely at odds with reality, even during the day. If it’s not too much to ask, I would like to understand if this is just my own issue, considering that the post has not received any replies, or if it is a widespread oddity that no one cares about. Either way, thank you anyway. Don’t get me wrong, you know I love this watch!
