Can't see ratings prompt

I have the following code to show a ratings prompt when the user comes back to the app a second time and hasn't seen the prompt. It asks the user to rate my app in the app store. I'm on the latest version of iOS.

When I call RatingPrompt.trackVisitAndShowPromptIfNeeded(), even though the conditions are met (the user hasn't seen the prompt and it's been more than 1 day since they first visited the app), the prompt doesn't show.

What am I doing wrong?

import StoreKit
import UIKit

struct RatingPrompt {
    private static let firstVisitKey = "firstVisitDate"
    private static let hasShownPromptKey = "hasShownRatingPrompt"
    private static let hasShownAfterFirstSummaryKey = "hasShownAfterFirstSummary"
    
    /// Call when user opens the app / visits a main screen
    static func trackVisitAndShowPromptIfNeeded() {
        let defaults = UserDefaults.standard
        let now = Date()
        
        // Save first visit date
        if defaults.object(forKey: firstVisitKey) == nil {
            defaults.set(now, forKey: firstVisitKey)
            return
        }
        
        // If already shown via visit or summary, do nothing
        if defaults.bool(forKey: hasShownPromptKey) {
            return
        }
        
        // Check if at least 1 day passed
        if let firstVisit = defaults.object(forKey: firstVisitKey) as? Date {
            let oneDay: TimeInterval = 60 * 60 * 24
            if now.timeIntervalSince(firstVisit) >= oneDay {
                requestReview()
                defaults.set(true, forKey: hasShownPromptKey)
            }
        }
    }
    
    /// Call when user reads their first book summary
    static func trackFirstSummaryRead() {
        let defaults = UserDefaults.standard
        
        // If already shown, do nothing
        if defaults.bool(forKey: hasShownPromptKey) || defaults.bool(forKey: hasShownAfterFirstSummaryKey) {
            return
        }
        
        // Show immediately on first summary read
        requestReview()
        defaults.set(true, forKey: hasShownAfterFirstSummaryKey)
        defaults.set(true, forKey: hasShownPromptKey) // ensure it won't show again
    }
    
    /// Internal helper to request review
    private static func requestReview() {
        if let windowScene = UIApplication.shared.connectedScenes.first as? UIWindowScene,
            let window = windowScene.windows.first {
            SKStoreReviewController.requestReview(in: window.windowScene!)
        }
    }
}

To review the app manually you should use your app’s URL. The built in controllers are subject to Apple deciding if it’s ok

// Replace the YOURAPPSTOREID value below with the App Store ID for your app.
// You can find the App Store ID in your app's product URL.
let url = "https://apps.apple.com/app/idYOURAPPSTOREID?action=write-review"


guard let writeReviewURL = URL(string: url) else {
    fatalError("Expected a valid URL")
}


openURL(writeReviewURL)
