Hey there,
Reviews can sometimes take longer, especially for new sellers. There’s some extra checks in place to prevent fraud. I’d suggest to wait a few more days.
It would be very handy if this button would say “in review” instead of published while in queue.
I completely agree that it would be nice if there was an indicator. Having said that, the button says “PUBLISHED” because your project is indeed published. You can share your page to other sites like social media, and users can purchase your project.
Hope that helps :)
