Call input.location.Start() but status keeps to be Stopped.

I'm trying to implement getting location feature. The code below works like a charm in test project but it doesn't work in my real project. Calling Input.location.Start() doesn't bring any effect to Input.location.status. This app has permission. Original both project works in Unity 2020.3.4f1. I changed Unity version of real project to 2020.3.13 but result is same.

RequestUserPermission works fine but calling Input.location.Start() seems not work.

There is use feature entry in AndroidManifest.

I wanna know what causes these different result in two project with same code. Any info is really helpful. Regards,
