Hello,
The Racial Justice bundle works differently than other bundles on our site. Due to the size of the bundle we made some technical and organization decisions to not automatically display all the projects in the bundle automatically.
Regarding other projects: it’s possible to buy things on itch.io without an account. This means that it’s possible for a previous purchase to not be linked to your account. If you’re able to access the purchases in the app then it sounds like the purchases are linked to you account. Otherwise, head to the download/purchase receipt page in your browser and ensure you click the button to link it to your account.
When a purchase is linked to your account, then the top of the page will display a banner saying that you own it with a direct link to the place to download it. In the app, the download button may display directly in the app’s UI.
The buy button will never disappear from the page, should you choose to support the project again or buy it as a gift for someone else.
Hope that helps
