Notifications not working

[WaniKaniNewbie]

The app does not notify when there are new items for review or study.

Is this because the app doesn't auto update in the background?

I seem to have to manually refresh to find out the current reviews and lessons

I also have this issue on a Galaxy S8 running Android P.
I have tried:
Opening the App and enabling notifications within it.
Opening my system notification settings and allowing notifications for the App.
Turning off Do not Disturb on my system.
Opening up mobile data and ensuring background data is enabled for the app explicitly enabling the App to transfer mobile data in the background

You must be on Android O or greater, i think the notifications are getting created in NotificationPublisher.java:

WaniKani-for-Android/WaniKani/src/tr/xip/wanikani/content/notification/NotificationPublisher.java

Line 79 in d79a4b4

void load(StudyQueue queue) {

However on Android O and above you need to create a notification channel to publish the notifications in, otherwise they won't be shown.
