Item sales have slowed down almost to a halt

I used to get a lot of traffic from Envato on my demo but it seems like recently over the past few months my traffic from Envato has nearly stopped entirely. I was wondering if this is part of the algorithm for new items to gain more visibility. I would love to hear any tips or tricks that can help bring back my visibility.

Here is a link to my item: https://codecanyon.net/item/order-taking-app-for-restaurants-and-shops-point-of-sales/16836918
