Been using a Vivosmart 4 for over a year now. Paired to my iPhone 13 Pro (and before that a 12-something) running Connect v220.127.116.11 I can't get a Pulse Oxygen number any later than about 3:30 AM for any night's sleep record.
Is there some setting that would allow a full night's record of this? I routinely sleep from ~ 9:45 PM until a 5:30 AM alarm on weekdays, maybe 6 or 6:30 AM on weekends but the pulse ox numbers stop at roughly the same time every night.
Seems ~ 6 hours is all it'll 'remember' then offload to the app. Why's that?
