App Stalls When Launching From Push Notification [iOS]

When sending a push to our app, it fails to load when opening the app from the push itself (swiping the push to the left on iOS or to the right and then "view"). Is this avoidable / has anyone else encountered this problem?

Our push code is as follows:

function initPushwoosh()
{
    //if android
    if (ionic.Platform.isAndroid()){
    var pushNotification = cordova.require("pushwoosh-cordova-plugin.PushNotification");

    document.addEventListener('push-notification', function(event) {
        swal(event.notification.title);
    }); 

    //initialize Pushwoosh with projectid: "GOOGLE_PROJECT_NUMBER", pw_appid : "PUSHWOOSH_APP_ID". This will trigger all pending push notifications on start.
    pushNotification.onDeviceReady({ projectid: "REDACTED", pw_appid : "REDACTED" });

    //register for pushes
    pushNotification.registerDevice(
        function(status) {
            var pushToken = status;
            console.warn('push token: ' + pushToken);
            window.localStorage['PendingToken'] = pushToken;
        },
        function(status) {
            console.warn(JSON.stringify(['failed to register ', status]));
        }
    );

    }

    //if ios
    if (ionic.Platform.isIOS()) {
    var pushNotification = cordova.require("pushwoosh-cordova-plugin.PushNotification");

    //set push notification callback before we initialize the plugin
    document.addEventListener('push-notification', function(event) {
        console.log("ios: i am listening");
        var notification = event.notification;
        console.log("ios:notification is " + notification);
        //clear the app badge
        pushNotification.setApplicationIconBadgeNumber(0);
    });

    //initialize the plugin
    pushNotification.onDeviceReady({pw_appid:"REDACTED"});

    //register for pushes
    pushNotification.registerDevice(
        function(status) {
            var deviceToken = status['deviceToken'];
            console.warn('registerDevice: ' + deviceToken);
            window.localStorage['PendingToken'] = deviceToken;
        },
        function(status) {
            console.warn('failed to register : ' + JSON.stringify(status));
        }
    );

    //reset badges on app start
    pushNotification.setApplicationIconBadgeNumber(0);
    }
}
