iOS crash after using Unity Ads 2019.2.12f1

Hi,

After implementing Unity Ads (downloaded from asset store). I'm getting the following crash on iOS:

Code (CSharp):

I've found the same error in this topic:
https://forum.unity.com/threads/ios...cpp-using-unity-2018-3b3.563707/#post-3741766

But it's about the 2018 beta. It talks about the Unity Analytics package that needs to be updated. The version that is in my project is 2019.2 verified.

Thoughts? Thanks.

 

OK, did some experimenting and it has nothing to do with the post I mentioned above.

I was calling

Code (CSharp):

1. Advertisement.Banner.Show();

without supplying a PlacementId value. Then I think when calling hide it crashes. Now when I provide PlacementId it doesn't crash. Is this desired behaviour? A fatal crash?

I'm leaving the banner out as it doesn't always display even and rolling an app out when I know it can fatally crash seems risky.

 

Thanks man! This solved the problem. Unity should handle this, btw
