I managed to get my Progressive Web App to send notifications to users via Web Push. However, it seems that the definable actions are not working. In Chrome, there is a button in the notification. If you click it, you get an overview of the available actions that the user can click. When I look at the notification on iOS, I only see the "View" action. My self-defined actions seem to be ignored and not displayed. Also, the "notificationclick" event should be executed by the browser as soon as the notification is clicked. In the Serviceworker I listened to the event and tried to link to a specific page of the PWA. In Chrome and Firefox this works fine. In Safari / iOS I only get to the start page of the PWA. Are the notification actions not yet supported with WebKit 16.4 ?
