Sleep sync.

try opening the sleep app on your watch. After that sync with GC app.

According to DC Rainmaker :

"home here there’s the updated sleep tracking. Previously Garmin only showed sleep tracking on their app, and not on the watch itself. Last fall Garmin introduced on-device sleep tracking to the Fenix 6, but then paused roll-out after running into some issues. Things resumed again with the Garmin Enduro about two months ago, and the train appears fully back on the tracks now with the Venu 2/2S. It sounds like Garmin is pretty confident in where they’ve got the algorithms to at this point to get the broader roll-out plans back on track (namely for the FR745/945)."

In any event, you’ll see your sleep status each day on the watch, first in the widget glances, and then by tapping on that widget glance for full information:

I can see my sleep on the watch. But my question is why i have to connect my watch to my computer and Garmin Express and do a sync to be able to see my sleep in my watch and phone/ipad? Just turn bluetooth on in my phone/ipad and do a sync does not let me see my sleep in my phone/ipad/watch so I have to go to the computer and sync!

You don't have to use Garmin Express. Open the Sleep Glance on your watch. Then sync over Bluetooth over Connect. Sleep data will be updated in the Connect app. I find it takes a few minutes to appear.

Hi, I wear venu 2s, sometimes widget glance for full information will appear but sometimes it's not. Do you have any idea why it happens?
