This morning I had to re-log into my fitbit account on my S24 which seemed odd. Now today it hasn't shown the more detailed sleep stages like, deep sleep, rem sleep etc.
I seem to recall something like this happening previously and I had to turn something on somewhere, in the settings (or similar) to give the app. access to things like heart rate data, but I can't remember where it was. can anyone help and does anyone know why the sudden change please?
