I have been tracking my sleep with S Health and a gear s3 for about a year now. All data synced to Sleep is just showing long grey bars that usually differ in width per night but are always the same for an individual night.
Is this as it should be or is something going wrong?
Hi, this is definitely wrong, there are no data. The grey bars are not data, they just depict whole hours (e.g. on the bottom graph on your screenshot it’s white bar from 14:37 to 15:00, grey bar from 15:00 to 16:00 and then another white from 16:00 to 16:39).
Could you please send us a debug log using menu > send wearable report?
