It seems to work but I have another problem now.
With PubCenter / Ads I cant use "any CPU" build anymore and need to tick x86, x64 and ARM separately. I tried to create 3 separate packages to make the download for each CPU type smaller but it does not allow me to upload separate packages. I have to tick all 3 at once and now get a huge file with about 3x the size of the app (cause it has all 3 in a bundle). Is it possible to prevent this somehow and make smaller packages?
My App has about 40MB but in the 3 CPU bundle I have to upload its 120 MB.
