Live Heart Rate while Dim

New Ultra 4 is not showing heart rate data on large or small complications while face is dim. I checked all the settings and still am having issues seeing it. The graph goes completely blank and the small circular complication just goes to the heart icon. I bought this Ultra to see more frequent heart rate data throughout the day like my Garmin can show. I do not want to have to tap and open up the Heart Rate app every single time.


Is this a planned future feature? (Live updating heart rates while dimmed) Otherwise I might just return and go back to Garmin.


Thanks

Update: went to Apple Store today, talked to the tech. He had another person with ultra 4 on watchOS 27 with the same issue. Then there was a guy with ultra 3 on watchOS 26 where it was working fine. So he confirmed it’s an OS issue that needs to be patched. He suggested that I go submit official feedback to Apple to escalate. I encourage everyone experiencing it to do the same to improve the odds of the fix.

no idea


these forums are user helping other users like yourself, it's sort of going to a physical apple store and asking other customers their advice

Same issue here, using ultra 4 with latest update of watchOS 27.0.1, modular ultra Watch face having heart rate as the middle complication. Tried restarting, checking/unchecking Heart Rate under Always On menu, changing complication back and forth, toggling low power mode on/off. Nothing.


While I realize that updating the graph every few seconds constantly might be taxing on battery, it can show increments each 5 mins unless I raise to wake, which will then measure the current rate. Blank heart rate complication is a major annoyance.

The watch is not measuring my heart rate at all. It’s doing it maybe once an hour unless I have the heart rate interface on. I slept on sleep mode and it took all of my vitals, except they didn’t measure my heart rate a single time during the night. I’m extremely disappointed.

I’m wondering if anyone has their heart rate displaying while dimmed, that would help narrow down the issue to it being specifically my device/settings vs a hard limitation set by Apple

No, it’s only showing and measuring my heart rate when I open the heart rate app on the watch

This is how it looks like. Just says Heart Rate and blank graph
