Unity Ads works in Unite, Android, but not iOS

Hey all, so I have been having issues with Unity ads only on the iOS version when converting to Xcode. Basically everything works fine in Android, Unity shows the ads are working when testing in it, but the moment I output the Xcode version and run it on my iPhone it no longer works. It works on my old version of the game (Which was running on 2018.3.0 f2 with Unity Ads 3.1 and still works on the store and when outputting it to my phone. The new version has a few changes to the game and some improvements but nothing should have been effected in ads. I checked the coding and I have the code Unity shows for the iOS version of the ads. The code for the ads is exactly the same. Any ideas?

Here is the code snippet from the game for the ads.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Advertisements;
//using GooglePlayGames; //Google play store
//using GooglePlayGames.BasicApi; //More Google Play

public class DeathManager : MonoBehaviour {

public static DeathManager dm;

public int deathCount = 1;
public int achieveCount = 0;
private int randNumber;
public static string gameId = "xxxxxx6";


// Use this for initialization
void Start () {
randNumber = Random.Range(7, 12);
if (dm == null)
dm = this.GetComponent<DeathManager>();

DontDestroyOnLoad(this);
if (FindObjectsOfType(GetType()).Length > 1)
{
Destroy(gameObject);
}
if (Advertisement.isSupported)
{

Advertisement.Initialize(gameId, true);
}

}

//Make a function to check to see if we need to play the Ads
public void CheckDeaths()
{
//incrememnt for achievemetn
achieveCount++;
if (achieveCount >= 20)
{
Social.ReportProgress("why1", 100, success => { }); // Die 10 times
}
if (achieveCount >= 200)
{
Social.ReportProgress("die2", 100, success => { }); // Die 100 times

}

if (deathCount >= randNumber)
{
Advertisement.Show();
deathCount = 1;
randNumber = Random.Range(7, 12);

}
else
{
deathCount++;
}
}
}

 

Yes, the one for iOS according to Unity is one that ends in a 6 while the android ends in 5. I made sure I have changed it. But I did try with both codes just to make sure.

 

Still having issues, any other suggestions? I have checked my codes and everything seems fine.

 

I will look through the logs, but did not see an error. I will look again and post a copy here. Its weird because it works in both Android and Unity but not the iOS version. Like I said it worked before and the only major changes we made between them is adding a pause at the beginning of each level with words on display. Not sure why that would cause a problem as the code for the ads has not changed at all.

 

The ads worked for me on iOS only after downgrading the version used by the package manager to 2.0.9.

 

Resolved the issue of the ads not showing up, seemed to start working after reentering everything and restarting it. Not sure what changed but it works now.
