MapBox not focusing camera on location right after allowing location permission - android-studio

Question

I have an Android app with a map in MapBox where I'm asking for the user's location. It pops up the permission request correctly, but on clicking "Allow" the camera shows a region of Africa, instead of the proper coordinates. It's taking the correct coordinates, it's just the camera that doesn't focus.
This is my LocationPermissionHelper
class LocationPermissionHelper(val activity: WeakReference<Activity>) {
private lateinit var permissionsManager: PermissionsManager
fun checkPermissions(onMapReady: () -> Unit) {
if (PermissionsManager.areLocationPermissionsGranted(activity.get())) {
Log.e("permission", "I'm already granted")
onMapReady()
} else {
Log.e("permission", "They are not granted")
permissionsManager = PermissionsManager(object : PermissionsListener {
override fun onExplanationNeeded(permissionsToExplain: List<String>) {
Log.e("permission", "Inside onExplanation needed")
Toast.makeText(
activity.get(), "You need to accept location permissions.",
Toast.LENGTH_SHORT
).show()
}
override fun onPermissionResult(granted: Boolean) {
Log.e("permission", "Inside onPermissionResult needed before if statement")
if (granted) {
Log.e("permission", "I just got granted")
onMapReady()
} else {
Log.e("permission", "Inside onPermissionResult needed NOT GRANTED")
activity.get()?.finish()
}
}
})
permissionsManager.requestLocationPermissions(activity.get())
}
}
fun onRequestPermissionsResult(
requestCode: Int,
permissions: Array<String>,
grantResults: IntArray
) {
permissionsManager.onRequestPermissionsResult(requestCode, permissions, grantResults)
}
}
And fragment:
class AddMapFragment : Fragment(R.layout.fragment_add_map) {
private lateinit var locationPermissionHelper: LocationPermissionHelper
private lateinit var binding: FragmentAddMapBinding

private lateinit var fusedLocationClient: FusedLocationProviderClient
