“The preview image looks like the design isn’t flat, please check the file and the export file.”
What is meant by image looks like the design isn’t flat?
Maybe he meant the “Design is flat” ??
Maybe…And this is just a guess.
From that quote, it would seem the reviewer didn’t even open the file and made an assumption on just the preview image…
At least that what it sounds like. But this is just a guess, best email the reviewer!
Ok I will contact reviewer thanks for your replies
