Adding sleep schedule to wrong day?

[hhall1992010]

I noticed about a week ago my Charge 4 is adding my sleep schedule to the current day, instead of the previous day? So it looks as if I have already slept for tonight, and had no sleep for yesterday at all. I tried changing the date on it manually on the app but then I lost my sleep score. Then the next night it did it again and so now there is a big gap and it appears as if I have went several days without sleep and it added it to the next day instead of the day before. What can I do to correct this? It is only my sleep that it is adding to the wrong days. I have also noticed that it is taking forever to get it to sync to my phone as well. I cant leave it synced all the time or else it drains my phone battery in a matter of a few hours it seems like so I usually just sync it every morning to get all the data from the previous day. But its taking up to 30 mins to get it to sync now.

Sleep is always credited to the day you wake up, so in the morning, the sleep you just got is considered today's (this morning's) sleep.

Okay so then technically all the other days are wrong then? Because I have only had it about 3 weeks and for the first like 2 weeks it was adding my sleep to the previous day. Like when I would sync it on Tuesday morning, it would add the sleep to Monday's day. But its actually supposed to have been adding that sleep to Tuesday?

Sorry but I can't follow what was happening previously.  However, sometimes it takes a while in the morning for Fitbit to get your sleep data (maybe waiting to be sure you are really up?), and if you are only syncing once a day, maybe when you synced, current sleep was not ready yet but it was loading sleep from previous day, if that made any sense.
