Apple Watch Ultra 3 + watchOS 27: Find My > Devices does not load correctly

I’m experiencing a reproducible issue with Find My on an Apple Watch Ultra 3 running watchOS 27.

The Find My app itself works partially:

• 
  
• People section loads correctly.
• 
  
• 
  
• Items section loads correctly and shows my AirPods.
• 
  
• 
  
• My own location loads correctly.
• 
  
• 
  
• The Devices section opens, and the map itself loads and responds to the Digital Crown.
• 
  
• 
  
• However, the device information/cards never appear in the foreground. The screen remains essentially empty while the map is visible.
• 
  

On my iPhone, Find My works normally and shows the current location of the Apple Watch Ultra 3.

I have already:

• 
  
• Restarted the Apple Watch normally.
• 
  
• 
  
• Force-restarted the Apple Watch.
• 
  
• 
  
• Verified Find My / Find My Network settings.
• 
  
• 
  
• Verified Location Services.
• 
  
• 
  
• Confirmed that the Apple Watch is correctly registered in Find My.
• 
  

None of these changed the behavior.

This makes it look less like a GPS, account, or Find My network problem and more like an issue specifically affecting the Devices section of the new Find My app in watchOS 27.

Apple’s own documentation says that in watchOS 27, Find My > Devices should allow users to scroll through their devices with the Digital Crown and see their locations on the map. If a device cannot be located, its last known location should be shown. 

watchOS 27 also introduced the new consolidated Find My app, combining People, Devices and Items into a single map-centric interface. 

Has anyone else with an Apple Watch Ultra 3 experienced the same behavior after updating to watchOS 27?
