No RC download appearing on my iPhone 15 pro max

So I’m currently on version iOS 18.1 (22B5034e) but don’t seem to be getting the RC download software update, is the because I’m on a higher version than RC?

stupid question I know…

I’ve tried downloading the profile from Apple developer but the profile never installs even if the iPhone restarts
