Health app overnight stopped syncing to iPhone

I use my Apple Watch to track my sleep, but overnight it stopped syncing data to my iPhone. I updated to iOS 26.1 last week and it was working just fine, so I don’t think that’s the cause. I’ve already tried turning off iCloud sync for Apple Health and confirmed that the Health app has all necessary permissions.


What’s strange is that my Apple Watch is still connected to my iPhone, and all the sleep data appears correctly on my iPad — which isn’t even paired with the watch. That suggests the data is being uploaded to iCloud, but it’s not syncing back to my iPhone.


Any advice would be appreciated.

Health App Not Syncing;


New iCloud Session(s):

Sign Out of iCloud in your Apple Watch. And then sign back in. If that does not work, then sight out of iCloud on all of your devices, and then sign back in, one-device-at-a-Time. It may need to resync.
