ARKit ARCoachingOverlayView ”Start Over” button in relocalizing not working

The method

Code Block 
func coachingOverlayViewDidRequestSessionReset(_ coachingOverlayView: ARCoachingOverlayView)

is never called when I conform to the ARCoachingOverlayViewDelegate protocol. The two other methods coachingOverlayViewWillActivate and coachingOverlayViewDidDeactivate are called correctly. The "Start Over" button which is displayed during relocalization is clickable, but the event does not trigger any action when tapped. Weirdly enough, sometimes the event will trigger, but then it is often up to 20 seconds after being clicked.

I am declaring my coachingoverlay like so

Code Block 
private let coachingOverlay = ARCoachingOverlayView()

In viewDidLoad I perform the setup

Code Block 
func setupCoachingOverlay() {
		coachingOverlay.session = sceneView.session
		coachingOverlay.delegate = self
		
		coachingOverlay.translatesAutoresizingMaskIntoConstraints = false
		sceneView.addSubview(coachingOverlay)
		
		NSLayoutConstraint.activate([
				coachingOverlay.centerXAnchor.constraint(equalTo: view.centerXAnchor),
				coachingOverlay.centerYAnchor.constraint(equalTo: view.centerYAnchor),
				coachingOverlay.widthAnchor.constraint(equalTo: view.widthAnchor),
				coachingOverlay.heightAnchor.constraint(equalTo: view.heightAnchor)
		])
		
		coachingOverlay.activatesAutomatically = true
}

And I conform to the protocol

Code Block 
extension ARView: ARCoachingOverlayViewDelegate {

I’ve basically followed how it is done in the Apple example project, where this problem is not an issue, but I can’t find the issue.
https://developer.apple.com/documentation/arkit/world_tracking/placing_objects_and_handling_3d_interaction

I’ve tried on devices using iPhone 7, 11 and 11 Pro with iOS 13 and iOS 14 beta, all experience the same problem.

I love this functionality but with this problem it unfortunately can not be used in production code.

What may be the problem?
