Historic Sleep score, graphs and other details have been removed from the app for older phones

[Guy_]

Since April 3rd the underlying Sleep stages and Estimated Oxygen Variation details are missing from the Fitbit App.

Something has been changed at the Google end, as this has never been the case before except in rare cases of a bad night's sleep but in this case it is not applicable.

Is it just processing issues at Google causing this disruption with the latest modifications for dealing with sleep?

It seems that people with older phones are impacted by the recent modifications to the sleep processing implemented at the Google server side and will no longer receive the historic sleep score details and graphs.

Following recent modifications in the Fitbit sleep processing at Google, the Sleep Stages graphs and Estimated Oxygen Variation are no longer provided to users with older Android phones.
