Description of Bug

Notification counter in the navigation drawer never seems to get updated despite API response data reflecting changes, unless you logout and login again.

Reproduction Steps

• Login to your AniList account and make a mental note of what the unread notification count is
• Interact with the app or website to get the notification count to increase
• Check the app and make sure that at least one notification check/profile request has been made
• See the notification count upon expanding the navigation drawer, notice that the unread amount doesn't change

Screenshots

Additional Context

• See notification provider for UI controller for icon and counter logic
• See data source class responsible for managing requests and persistence of the viewer class
• See notification entity reference table that holds the user_id and notification count for a given user_id, this is only applicable to the authenticated accounts/profiles

We utilise relations to combine the user and notification entity tables

anitrend-v2/app-data/src/main/kotlin/co/anitrend/data/user/entity/view/UserEntityView.kt

Lines 42 to 49 in bf2d52d

	internal data class Authenticated(
	@Embedded override val user: UserEntity,
	@Relation(
	parentColumn = "id",
	entityColumn = "user_id"
	)
	val notification: UserNotificationEntity,
	) : UserEntityView()

Perhaps it's easier to use a simple shared prefs to store our notification unread count, that way we don't need to concern our selfs with complex database queries
