My Fenix 7 recorded/analysed my sleep very well for about a month. Now, however, it is suddenly finding it extremely difficult to recognise my sleep. Often it doesn't show any sleep at all in the morning and if it does, then usually with large gaps. My heart rate is measured, but often around 80BPM. During the day my heart rate is normal. I haven't changed the strap or the way I wear it. Does anyone know what could be wrong?
