Messenger Not Updating on mobile

Basically what's happening is this:

• I have messenger open in Chrome but it's only open in the background.
  • Aka it's not the application I'm in.
• I get a push notification on my phone that I have a new message.
• I open up Chrome with the messenger still open in the browser but it doesn't show that I have a new message in the chat window without refreshing the page.
  • Once I refresh the page, then it shows that I have a message in the actual chat window.

I know if I clicked on the push notification, it would open up a new browser window and the message would be there. The problem with that is, it ends up opening a ton of browser windows, instead of going to the one that's already open...

Not sure how to fix that...
