Android Notification does not shown on background/killed states

Bug Report

Android Notifications does not shown on background and killed states on latest 4.0.0 version.
The phone receives the notification (I see it via doing *#*#426#*#*).

Expected Behaviour

It should be shown when sending via data tag.

Actual Behaviour

It is not shown when the app is background, but it is shown when I send FCM push with notification tag.
Also, I noticed that, when I send the push message and it is not delivered, then when I open the app again, the app starts from the begining (splash screen). I mean, when the app receives any push message when it is on background, it behaves as it is killed and starting again.

Platform and Version (eg. Android 5.0 or iOS 9.2.1)

I tried it on Android 7, 8, 10, 11. All same behaviour.

(Android) Device Vendor (e.g. Samsung, HTC, Sony...)

Samsung and RedMi.

Sample Push Data Payload

{
   "message":{
"token":"xxxxxxxxxx",
      "android":{
         "priority":"HIGH",
         "data":{
            "title":"TITLE (title): ı.I.i.İ.ğ.Ğ.ü.Ü.ş.Ş.ç.Ç-X",
            "message":"BODY (message): ı.I.i.İ.ğ.Ğ.ü.Ü.ş.Ş.ç.Ç-X",
            "sound":"notification",
            "icon":"icon",
            "android_channel_id":"nc-default",
            "channelId":"nc-default",
            "badge":"1",
            "notification_count":"1",
            "a":"27",
            "v":"4521960",
            "notId":"39459313",
            "vibrate":"false"
         }
      }
   }
}

Confirmed same behaviour.
This is somewhat documented here: https://github.com/havesource/cordova-plugin-push/blob/master/docs/PAYLOAD.md#notification-vs-data-payloads

In previous versions of Android/Cordova, sending the title/body etc. only in the data key as documented, the notification would be displayed when the app was in the background.

Currently, when sending with the notification key, the plugin behaves as documented, the Android system will display the notification, but the plugin's handlers don't run.

Also, I noticed that, when I send the push message and it is not delivered, then when I open the app again, the app starts from the begining (splash screen). I mean, when the app receives any push message when it is on background, it behaves as it is killed and starting again.

Noticed this also, sending the notification with details in the data key only - when received while the app is in the background - the app crashes.
