Hello,
Paid games may take some time to appear in our search and browse pages, we may require a human to check them before they go up. We go through games throughout the day. It's not necessary to upload images to your profile or compress PDFs. (Although, if you do not provide a cover image your game may not be shown in search). It's likely your page was reviewed while you were experimenting and you came to the wrong conclusion.
Note that this only affects games showing up by browsing through our site, direct links will work as intended.
Thanks
