When I get am SMS text message I get a small notification at the top of the screen. However when I get a WhatsApp message the notification takes over the entire screen. If I get a flurry of messages my phone is basically unusable for a while, which is annoying if I'm trying to do something else.
I don't want to turn off WhatsApp notifications completely I just want them to be less prominent. Is this possible? I have a Pixel 3 so I'm running stock Android.
