There could be different reasons for this.
1. Have you downloaded the Sdui app from the AppStore to your mobile phone?
If you use Sdui in a browser (e.g. Google Chrome, Firefox, Safari etc.), you will not receive push notifications. These only apply to apps.
2. Are you logged into Sdui?
If you log out of Sdui on your mobile phone, you cannot receive a push notification. Similar to WhatsApp, the application needs to stay open in the background so that you can receive notifications.
3. Have you activated notifications in the Sdui app?
In the Sdui app, go to Settings using the drop-down menu in the top right corner. There you have to click on “Notifications”.
Now you can choose for which scenarios you would like to receive push notifications. You can choose between “News & Announcements” and “Groups & Individual Chats”.
4. Have you allowed push notifications on your mobile phone for the Sdui app?
To do this, open your mobile phone settings and check whether you have allowed notifications for Sdui.
If all conditions are met and you still do not receive a push notification, then reinstall the Sdui app from the AppStore / PlayStore. In most cases, this should solve the problem.
