Banner and Reward ads in android

Hi all,
maybe you will be able to help me make some sense into it

I'm trying to add the unity ads to my game
I have reward ads and they are working find and I want to add banner ads
My understanding is that I need to use the monetization package from the store
but when I use it my game crush on load...

I tried it in a new project and the same problem happened...

All I did was creating a script and initialized the classes in the start method (like it states in the tutorial)

Monetization.Initialize(_gameStoreId, false);
Advertisement.Initialize(_gameStoreId, false);

but when I do that my game freezes on load
and each alone works fine...


any reason for that to happen?
what do I need to do to be able to have both banner and reward ads in my game?

 

Probably want to check in the Ads forum, this has been discussed. https://forum.unity.com and look for Unity Ads
