Sleep data changes the day after the next - Connect Web - REM sleep appears - totals change

Former Member over 5 years ago

The first Sleep diagram is directly after first Sync from the Watch, the second picture is the data of the same night with the same data but a day later, all of a sudden there is REM sleep and a completely different start and end time and totals.

Maybe I do something wrong, or have other users experienced the same?

Right after sync the sleep data seems very similar between vivoactive 4 and Fitbit. Then a bit later the server does its "magic" and completely messes up the record. Why has this not been fixed? For over a year?!

Same thing happened to me. But now instead of the 7h I was sleeping it recalculated 12h after some time.

My sleep points total yesterday morning was 66. This morning the total for the same night was 1 (one). Garmin 7X Sapphire Solar. My sleep total is rarely good but this is ridiculous for it to change. I had 8:01 sleep, deep 0 (zero) REM 3:15, and a few minutes awake. Why would it change so drastically?

Same issue here

and to add insult to injury, manually correcting sleep data does not correct sleepscore
