Uwb App (NIpeekaboo) doesn't work in iOS 14.2.1

when i check NIpeekaboo before update iOS to latest, it worked well.

but if i push app after update iPhone12 to iOS 14.2.1 and Xcode to 12.2, it stops on "discovering peer".

air-drop is working but NIpeekaboo is not working.
how can i test NIpeekaboo?
Also not able to get past this, but not sure I'm running it the right way to begin with.
Got it working by changing to iOS 14.0.1 for both simulators like you said. iOS 14.3 still does not work and must be a bug.

You need to run two iOS Simulators running iOS 14.0 (I used two iPhone 11s) for the Discovering Peers message to go away and the app to start running.
