I have finally created my 32 page animated children's book app and it is time to publish on both platforms, but when I apply the different rendition sizes sometimes there is white around the side or top. I only have a short time to update my app or it will be removed permanently!
It doesn't appear there are any options available for the newer devices. What are my options?
Is there a way to create one universal size that will fit all devices?
thank you!
