@dfghj44444 if you are facing the similar issue as #5144.

If not, you can reopen it.

[dfghj44444]

It's not about focus, just navigationStarting never works in this scene. @sivMSFT and I have no permission to reopen. Thus I created a new one #5155

[sivMSFT]

@dfghj44444, I apologize for the inconvenience caused by mistakenly closing the issue. I am reopening the issue and closing #5155
