Sleep data upload to Health app when alternating Galaxy Watches

[userRq2PcNjYC9]

Hello,

So Im aware this is a fringe case issue, but its one I deal with. I didnt trade in my Watch 7 when I got the Watch 8, I also didnt trade in my S25 Ultra when I bought a Fold 7. 

Since I have 2 watches and 2 phones, I keep the watches linked to their respective phone: W7-S25 and New W8-Fold7...

What Im noticing is even though Im logged in to the same Health app account under my Samsung login, I notice that both watches record and upload that sleep data (or activity data throughout day) seperately as if Im using two totally seperate Health app accts.

Why is this?

Main Q: Is there a way to merge all data under my Samsung Health profile, all sleep data from all devices linked/signed in under that same Samsung Health acct?

It seems weird that it seperates the data? 

Fir example, Ill sleep with Watch 7, then wear Watch 8 during day. My Health app doesnt show the data from both...

Thanks for any info and assistance! Much appreciated!

I have 2 watches linked to a single phone and have no issue. I would recommend you do that.

Does sleep tracked with one show up on the other? How to sync? I use my Fit3 to record sleep, but in the morning I switch to Watch 4 Classic, and it doesnt show the sleep data. The phone app however, shows it.

@kasamakasam321 I always wear the Galaxy Ultra for sleep tracking since it has sensors the GW 7 does not. I have to admit that I never checked the GW 7 to see if the sleep data was synced over. I have had no need to check the sleep info on the watch. I just review that information on my Fold 7.

@kasamakasam321 I just checked and the sleep data recorded by my GW Ultra does show up on my GW 7.

You have "Sync to Samsung Cloud" disabled on your devices. Enable it by following these steps:

1. Open Samsung Health.
2. Click 3 Dots menu, and enter settings.
3. Up top, directly under Samsung Account, there is a Sync with Samsung Cloud" toggle. Turn it on.

Ensure you do this on your Fold 7 and S25.
