What happened with User Nearby Interaction framework on IOS 15?

I installed an official app made by the apple from there https://developer.apple.com/documentation/nearbyinteraction/implementing_interactions_between_users_in_close_proximity on my IOS 15 iPhone 11 and it doesn't work.

Every time when NISession try to run it turns to suspended mod with no reasons.

Does anyone have idea?

Are you perhaps based in one of the "unavailable" countries?
