Damn, we just released a new version yesterday. I am wondering on which version u r. If you open Package dependencies -> Pendo -> Package what is the url u have there? Strange I cant reproduce any thing similar

[MikePendo]

Ok will fix in couple of minutes. The interesting thing is how do we get to it, any chance u could share code snippets of your app structure. i.e the initial code of your view hierarchy not the content BUT the high level design u r using. For instance in my sample app I have the following:

@main
struct AvocadosApp: App {
    let persistenceController = PersistenceController.shared
    @UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
    @State var selected = 4
    var body: some Scene {
        print("AvocadosApp body entry")
        return WindowGroup {
            WithPendo() {
                return TabView() {
                       let _ = print("TabView1111")
                       AvocadosView().tabItem {
                           Image("tabicon-branch")
                           Text("Avocados")
                       }.tag(0)

                       ContentView(facts: factsData, recipes: recipesData).tabItem {
                           Image("tabicon-book")
                           Text("Recipes")
                       }.tag(1)
                       .navigationTitle("Recipes")

                       RipeningStagesView().tabItem {
                           Image("tabicon-avocado")
                           Text("Ripening")
                       }.tag(2)

                       SettingsView().tabItem {
                           Image("tabicon-settings")
                           Text("Settings")
                       }.tag(3)

                       TestView().tabItem {
                           Image(systemName: "pencil.circle")
                           Text("Test")
                           //Label("Editor", systemImage: "pencil.circle")
                           //Text("Editor")
                       }.tag(4)
                   }
                   .edgesIgnoringSafeArea(.top)
                   .accentColor(.primary)
                   .onOpenURL(perform: handleURL)
            }
        }
    }

[MikePendo]

please use the latest version it should be 2.20.0.6599

[ondrejstasek]

please use the latest version it should be 2.20.0.6599

Looks good 👍🏻

[MikePendo]

@ondrejstasek any chance u could share a small high level structure of your app (the initial part) . I would like to understand how do we got to this case?
