Basically push notification will work like this. It sends notification from the site using our Push Notification plugin refer this: https://wplms.io/support/knowledge-base/wplms-push-notifications/Example: if you subscribed course from the instructor or by the user , the User will get a notification on the App.
There are multiple touchpoints, You can find here: https://prnt.sc/phswe8 and enable notification.
You have just to enable this and the user will able to get notification regarding these settings.
We have already added the push notification feature But it is in the development phase because ionic has released its new version so that it affects our build APK process. We are working to resolve this issue.
