Background Tasks in SwiftUI iOS 16

After following along with the documentation and WWDC22 video on using the new SwiftUI Background Tasks API. My application was successfully updating in the background, then I ran into an issue where the data won't update resulting in a progress view showing and no new data being fetched but will eventually correct itself which doesn't seem right. See below screenshots below.

struct DemoApp: App {
    @StateObject var viewModel = ViewModel()
    var body: some Scene {
        WindowGroup {
            ContentView()
                .environmentObject(viewModel)
        }
        .backgroundTask(.appRefresh("myapprefresh")) {
            await viewModel.fetchData()
        }
    }
}


class ViewModel: ObservableObject {
    @Published var pokemon = PokeAPI(name: "", sprites: Sprites(frontDefault: ""))
    
    func fetchData() async {
        URLSession.shared.dataTaskPublisher(for: request)
            .map{ $0.data }
            .decode(type: PokeAPI.self, decoder: JSONDecoder())
            .replaceError(with: PokeAPI(name: "", sprites: Sprites(frontDefault: "")))
            .receive(on: DispatchQueue.main)
            .sink(receiveCompletion: {_ in
            }, receiveValue: { value in
                self.pokemon = value
            }).store(in: &cancellables)
    }
}
