Unable to upload graphics

I am newly approved and am unable to upload graphics to the themes studio, I created them in Illustrator. Can anyone give me a rule of thumb on the size/resolution when creating your graphics?

There are a lot of places to add graphics, with lots of sizes and formats… Where in particular are you trying to add?

You can’t load .AI ( Adobe Illustrator Artwork) files into GTS, they typically need to be PNG, JPG or 9-patch.
