Several months ago, I bought a game on sidequest called "To The Top" for 15 dollars. Afterwards, I was able to install it on my headset (I use an Oculus Quest 2) and I had no issues with it.

Recently, the game had stopped working (Infinite loading screen), so I tried to uninstall the game and reinstall it through sidequest. However, when I tried to reinstall it, I get told that the game is now on the App Lab and I still need to purchase it before I could download it.

Why do I need to purchase the game when I already have? The game is literally in my library and has an option to download it. But when I choose the option, it just takes me to the store and asks me to buy the game. Is there any way to fix this?

I have proof of purchase, as well as an oculus key that I tried to use but I got an error instead. Any help would be appreciated, I can't afford to repurchase the game even though I've already bought it before.
