From what I understand from the documentation, "all current sales are listed on the itch.io sales page."
I'm currently running a sale of a single asset and a second sale of a bundle of assets, and neither is visible on the Sales page or the Bundles page. I've had significantly less purchases than previous sales, which is how I noticed that they're not visible on these pages. Adjusting the dates to end the sales and restarting them had no effect. The sales had been running for several days before I checked the Sales/Bundles pages.
Is this a bug, or is the documentation incorrect?
