    this error only appears when i call unity ads banner first time, if i close the game and reopen it , everything works fine, also if i didn't call the unity ads banner and instead i call other advertisers banner the game works fine without this exception, also i tried to use old version of the unity monetization asset but the same problem, is there any things can help to fix this? thank you

    Unity Monetization : 3.4.4
    Unity Version : 2018.4.14f1

    Can you share the code you using to reproduce this. Also some more details about your setup since that stacktrace makes it look like your not using a direct integration of UnityAds which is all we would be able to support you on.

    I am facing the same error. this is my code
    public void ShowUnityBanner()
    {
    StartCoroutine(ShowBannerWhenReady());
    }
    IEnumerator ShowBannerWhenReady()
    {
    Advertisement.Banner.Load();
    while (!Advertisement.IsReady(unityBannerId))
    {
    yield return new WaitForSeconds(0.5f);
    }
    Debug.Log("Banner ready");
    Advertisement.Banner.Show(unityBannerId);
    Advertisement.Banner.SetPosition(BannerPosition.BOTTOM_CENTER);
    }

    I'm not sure this is the cause of the issue, but one thing you might try is calling Advertisement.Banner.SetPosition before showing the banner.

    In addition, I would recommend calling Load before Show and using the BannerLoadOptions to make sure a banner ad has been loaded successfully before trying to show it.
