1 call of showToast() does not fire a Toast Notification, 2 calls of showToast() fires 2 Toast Notifications...

[rnewendyke]

I am working with this library for the first time (am also new to c++) and am running into an issue where the recommended code for usage will not send a toast notification, but including a second line of

WinToast::instance()->showToast(templ, handler)

causes 2 toast notifications to fire. Trying to understand what the root cause of this is so that I can resolve the issue I am experiencing here...

Code I have been using and experiencing the issue with is below and my compiler is set for c++20:

int main() {
    if (!WinToast::isCompatible())
    {
        std::wcout << L"Error, your system in not supported!" << std::endl;
    }

    WinToast::instance()->setAppName(L"WinToastExample");
    const auto aumi = WinToast::configureAUMI(L"mohabouje", L"wintoast", L"wintoastexample", L"20161006");
    WinToast::instance()->setAppUserModelId(aumi);

    if (!WinToast::instance()->initialize())
    {
        std::wcout << L"Error, could not initialize the lib!" << std::endl;
    }

    CustomHandler* handler = new CustomHandler;
    WinToastTemplate templ = WinToastTemplate(WinToastTemplate::Text02);
    templ.setTextField(L"title", WinToastTemplate::FirstLine);
    templ.setTextField(L"subtitle", WinToastTemplate::SecondLine);

    WinToast::instance()->showToast(templ, handler) // when this line is commented out, 0 toast notifications fire when compiled exe is run, when this line is included, 2 toast notifications fire when compiled exe is run

    if (!WinToast::instance()->showToast(templ, handler))
    {
        std::wcout << L"Error: Could not launch your toast notification!" << std::endl;
    }
}

definition of customHandler for reference (copy/paste from WinToast/example/qt-gui-example/WinToastExample/mainwindow.cpp):

class CustomHandler : public IWinToastHandler {
public:
    void toastActivated() const {
        std::wcout << L"The user clicked in this toast" << std::endl;
    }

    void toastActivated(int actionIndex) const {
        std::wcout << L"The user clicked on button #" << actionIndex << L" in this toast" << std::endl;
    }

    void toastFailed() const {
        std::wcout << L"Error showing current toast" << std::endl;
    }
    void toastDismissed(WinToastDismissalReason state) const {
        switch (state) {
        case UserCanceled:
            std::wcout << L"The user dismissed this toast" << std::endl;
            break;
        case ApplicationHidden:
            std::wcout << L"The application hid the toast using ToastNotifier.hide()" << std::endl;
            break;
        case TimedOut:
            std::wcout << L"The toast has timed out" << std::endl;
            break;
        default:
            std::wcout << L"Toast not activated" << std::endl;
            break;
        }
    }
};

Any help that anyone can offer is greatly appreciated.
