Playing Roblox on a school Chromebook can be rather tricky. These Chromebooks may come with built-in safeguards that prevent you from accessing games and certain websites.

Install the Roblox APK to avoid using Google Play Store, but be advised of the risks of downloading APKs from third-party sites.

If Roblox is not downloading or installing on your Windows 11/10 PC, restart your PC and if that doesn't help, use the fixes discussed here.
