Today I was reimplementing my Mopub implementation, that handles my Amazon ads too. Unfortunately with the new Mopub SDK you can't add a view to the layout before a Ad is requested. This means that the SIZE_AUTO does not work. I read the info about that in the Amazon SDK Readme, but still don't understand why I can't manually give the available height and width to the AdLayout, so it knows what to select? For now I will calculate it myself I guess.
