I had to factory reset my phone and it has change the settings on my messaging app.
If I was on my phone and got a normal message or WhatsApp it would pop up at the top and I could reply, close or mark as read without actually going on the app or if it was locked the screen would light up to tell me I had a message then sleep again. Now it just shows me the message. I've tried to get it back but not too sure how I done it or if it's a new update.
Sorry, I'm do not understand completily, today I had three incidences about Whatsapp Notification Auto Changes, could be possible some changes about it from Whatsapp.
