Age-restricted Roblox download issue on iPad

We tried to download Roblox, but their was an age restriction. We approved the age restriction and it said it downloaded. We tried to open the app, but it wouldn’t let me. Then it deleted itself from my Home Screen. But I still can’t download it again. Please help.
