Error while uploading tvOS app
Seems that making all layers of the icon full size solved the problem. Means not using the location of the layer but making the asset in a way the location is already on the full sized layer.
Just to make clear, All layers of the small icon (400 x 240 pixels) are with 400x 240 size with transparency except for the background layer which is without transparency offcourse.
Seems like a very odd bug so I though publishing it.
