title: Android Firebase notification gives default icon
body: <p>I have a problem with my Firebase notification icon. Until now it only shows a default android icon when I sent a notification. It looks like this:</p>
  
  <p><a href="https://i.stack.imgur.com/jbIpj.jpg" rel="noreferrer">https://i.stack.imgur.com/jbIpj.jpg</a></p>
  
  <p>But that is not even an icon I use. I changed the icons multiple times in "Image assets" but it keeps comming up like this...</p>
  
  <p>What am I doing wrong? Because the only thing I can find on the internet is that people get a gray icon instead of their own.</p>
