When trying to select it, it says Unable to set beta update
Unable to apply WatchOS 11 beta
Can you provide some more information about what you're trying to do and where you're trying to do it? Are you saying that you're trying to install the watchOS 11 beta on an Apple Watch, and that you're getting an error message that the update is not available? If so, what model iPhone and Apple Watch are you using? Has the iPhone been updated to iOS 18 already?
