Async Scene Load for Gear VR

Hi all, I am relatively new to Unity and one of my scenes in the gearvr consistently loads very slowly.

I have modified the script to have the next scene load asynchronously but now instead of waiting for the scene change parameters I have set up (either clicking on a mesh renderer or 30 seconds into the scene) the new scene transitions as soon as its finished loading even though I set "allowSceneActivation" to false unless one of those two aforementioned conditions are met.

Below is the script. Any thoughts/ideas about how I can correct this (load the new scene asycnhonously but still keep the scene transition triggers I have created) I would be greatly appreciated!

Thank you!

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.SceneManagement;

public class CameraRaycast_Earth: MonoBehaviour {

 public MeshRenderer rend;
 public bool hovering;
 public bool hoveringOld;

    private float intervalMax = 30.0f;
 private float currentTimerValue = 30.0f;
 AsyncOperation asyncLoad;

 void Start() {
     asyncLoad = SceneManager.LoadSceneAsync("BK_LightsOffRoadSign");
     asyncLoad.allowSceneActivation = false;
 }

 // Update is called once per frame
 void Update() {
     Ray ray;
     RaycastHit hit;
     ray = new Ray(this.transform.position, this.transform.rotation * Vector3.forward);
     if (Physics.Raycast(ray, out hit) && hit.transform.tag == "Clickable")

     {
         hovering = true;
    
         if (Input.GetMouseButtonDown(0))
         SceneManager.LoadScene("BK_LightsOffRoadSign");
         asyncLoad.allowSceneActivation = true;
         
     } 

     else{
         hovering = false;
     }

     if (hovering != hoveringOld) {
         if (hovering == true){
             rend.material.color = new Color(1f, 1f, 1f, .6f);
            
         }

         if (!hovering){
             rend.material.color = Color.clear;
             }
         }
         hoveringOld = hovering;

     if (currentTimerValue >= 0.0f)
     {currentTimerValue = currentTimerValue - Time.deltaTime;
     } 
     else if (currentTimerValue < 0.0f){
     SceneManager.LoadScene("BK_LightsOffRoadSign");
     asyncLoad.allowSceneActivation = true;
     }    
 }
