I bought a premium theme but it was through the Microsoft Store, I logged into my Real Dash account thinking it would be there, but it wasn’t. Are themes purchased through other platforms such as the App Store (IOS), Play Store (Android) and Microsoft Store (Windows) cross-platform? If so, how can I do this?
Yes, cross selling is prohibited by store rules. See this discussion:
