For the last five nights, I've removed my VivoActive 3 before I go to sleep as I always do, but instead of realising this as it used to do, it's now thinking I'm in deep sleep for eight hours (I could only wish for that kind of sleep!). I'm not sure why it thinks my bedside table has a pulse, but I can't work out how to: a) alter the settings so it doesn't do this any more, or b) remove the data it has erroneously recorded from the app, which only enables me to change the time I went to bed and woke up! This has never happened before. I've had the watch for about three months. Can anybody help by offering a solution or possible reason for this please?
