Trying to hide "Remove Ads" button whilst ads are switched off but not staying hidden

Hi!

So I have this script that removes ads for 10 minutes if the player has watched a rewarded ad:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.Advertisements;
5. using System;
6.  
7. public class AdManager : MonoBehaviour
8. {
9.     private static int loadCount = 0;
10.     private static bool noAds = false;
11.     private static DateTime noAdsTime = new DateTime();
12.  
13.     void Start()
14.     {
15.         DateTime currentTime = DateTime.Now;
16.  
17.         if (noAdsTime != new DateTime())
18.             noAds = DateTime.Compare(currentTime, noAdsTime) < 0 ? true : false; //DateTime.Compare returns less than zero if currentTime is earlier than noAdsTime.
19.  
20.         if (loadCount % 5 == 0 && noAds == false)  //  show ad every 5th time
21.         {
22.             ShowAd();
23.         }
24.         loadCount++;
25.     }
26.  
27.  
28.     public void ActivateNoAds(int minutes)
29.     {
30.         Advertisement.Show();
31.         DateTime currentTime = DateTime.Now;
32.         noAdsTime = currentTime.AddMinutes(minutes);
33.  
34.     }
35.     public void ShowAd()
36.     {
37.         if (Advertisement.IsReady())
38.         {
39.             Advertisement.Show();
40.         }
41.     }
42. }

That works fine. And now I am trying to hide the "Remove Ads" button during the 10 mins of no ads. I have tried to copy the structure of the above script to hide the button for 10 mins too... And I can get it to hide but the next time the player lands on game over the button appears again (but the ads are still off). I have tried its own script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using System;
5.  
6. public class AdsRemoveButton : MonoBehaviour
7. {
8.  
9.     private static bool noButton = false;
10.     private static DateTime noButtonTime = new DateTime();
11.  
12.  
13.     void Start()
14.     {
15.         DateTime currentTime = DateTime.Now;
16.  
17.         if (noButtonTime != new DateTime())
18.             noButton = DateTime.Compare(currentTime, noButtonTime) < 0 ? true : false; //DateTime.Compare returns less than zero if currentTime is earlier than noAdsTime.
19.     }
20.  
21.     public void ActivateNoButton(int minutes)
22.     {
23.  
24.         DateTime currentTime = DateTime.Now;
25.         noButtonTime = currentTime.AddMinutes(minutes);
26.         GameObject.Find("Remove Ads Button").transform.localScale = new Vector3(0, 0, 0); // Hide button
27.  
28.  
29.     }
30. }

And a combined script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.Advertisements;
5. using System;
6.  
7. public class AdManager : MonoBehaviour
8. {
9.     private static int loadCount = 0;
10.     private static bool noAds = false;
11.     private static DateTime noAdsTime = new DateTime();
12.     private static bool noButton = false;
13.     private static DateTime noButtonTime = new DateTime();
14.  
15.     void Start()
16.     {
17.         DateTime currentTime = DateTime.Now;
18.  
19.         if (noAdsTime != new DateTime())
20.             noAds = DateTime.Compare(currentTime, noAdsTime) < 0 ? true : false; //DateTime.Compare returns less than zero if currentTime is earlier than noAdsTime.
21.  
22.         if (noButtonTime != new DateTime())
23.             noButton = DateTime.Compare(currentTime, noButtonTime) < 0 ? true : false; //DateTime.Compare returns less than zero if currentTime is earlier than noAdsTime.
24.  
25.         if (loadCount % 5 == 0 && noAds == false)  //  show ad every 5th time
26.         {
27.             ShowAd();
28.         }
29.         loadCount++;
30.     }
31.  
32.  
33.     public void ActivateNoAds(int minutes)
34.     {
35.         Advertisement.Show();
36.         DateTime currentTime = DateTime.Now;
37.         noAdsTime = currentTime.AddMinutes(minutes);
38.      
39.  
40.     }
41.  
42.     public void ActivateNoButton(int minutes)
43.     {
44.      
45.         DateTime currentTime = DateTime.Now;
46.         noButtonTime = currentTime.AddMinutes(minutes);
47.         GameObject.Find("Remove Ads Button").transform.localScale = new Vector3(0, 0, 0); // Hide button
48.  
49.  
50.     }
51.  
52.     public void ShowAd()
53.     {
54.         if (Advertisement.IsReady())
55.         {
56.             Advertisement.Show();
57.         }
58.     }
59. }

Please forgive my probably dumb mistake. I am very much a beginner.

I am assigning these to the button's On Click and getting no errors so I don't know why it is not working? The

Any help much appreciated!

Thanks!
