I was running into this same problem and figured out it was caused by calling the registration methods on Notifications.events() multiple times and then receiving a push notification. In my case, these event listeners were initialized inside a useEffect hook that would re-trigger every time the app was backgrounded and then foregrounded. I solved it by moving the handlers to a useEffect hook without any dependencies.

Example:

useEffect(() => {
  Notifications.events().registerNotificationReceivedForeground(() => { ... });
  ... etc
},[]);
