Upscale 2× makes images bigger, up to 8 megapixels. This image is already 8 megapixels or more, so it is large enough for every platform size in Studio. Nothing was charged.
What to do
Open the image in Assets or on the Studio page.
Under Export for a platform, choose the size you need.
Tap the download button, which shows the size, such as Download 1080×1350.
Studio saves it at the exact pixel size the platform uses.
