showManageSubscriptions has a phantom sheet before displaying

[markbattistella]

Describe the bug

When calling Purchases.shared.showManageSubscriptions() a phantom sheet appears, then the manage sheet appear over the top. When dismissing the manage sheet animates off but then the phantom moves off.

Not sure if this is a full RC issue or if it is the underlying Apple API which is causing it.

Hi @markbattistella, thanks for reporting! This appears to be a bug with StoreKit - we're able to reproduce the issue without the RevenueCat SDK with this sample code:

import SwiftUI
import UIKit
import StoreKit

struct ContentView: View {
    var body: some View {
        VStack(spacing: 16) {
            Text("These buttons will show an empty sheet before showing the manage subscriptions sheet on top of the empty sheet.")
                .multilineTextAlignment(.leading)

            Spacer()
                .frame(height: 32)

            Button {
                Task { @MainActor in
                    let activeWindowScene = UIApplication.shared
                        .connectedScenes
                        .filter { $0.activationState == .foregroundActive }
                        .first as! UIWindowScene

                    try await AppStore.showManageSubscriptions(in: activeWindowScene)
                }
            } label: {
                Text("Show Manage Subscriptions with\nStoreKit.AppStore.showManageSubscriptions(in:)")
                    .multilineTextAlignment(.center)
            }

            Spacer()
                .frame(height: 32)

            Button {
                Task { @MainActor in
                    let activeWindowScene = UIApplication.shared
                        .connectedScenes
                        .filter { $0.activationState == .foregroundActive }
                        .first as! UIWindowScene

                    try await AppStore.showManageSubscriptions(in: activeWindowScene, subscriptionGroupID: "abc123")
                }
            } label: {
                Text("Show Manage Subscriptions with\nStoreKit.AppStore.showManageSubscriptions(in:subscriptionGroupID:)")
                    .multilineTextAlignment(.center)
            }
        }
        .padding()
    }
}

So far, we've only seen this happen in the sandbox environment - have you observed this happen in either the TestFlight or production environments?

By the way, we've submitted Feedback FB20471367 to Apple to report this issue to them 👍

[markbattistella]

thanks @fire-at-will for looking into it!

Yeah I have in production - but if it is a bug in StoreKit then not much RC can do about it.

Did you need anything to aid in the FB?

Hey @markbattistella, I think we have all of the information we need for now for our Feedback ticket. I'll keep this issue open for a while and will let y'all know if we find a workaround or if we receive additional information on our Feedback ticket. Thanks!
