iOS : notifications appears twice

Hi,
I'm not sure if it's a issue due to the lib or if it's a iOS normal behavior....
1- I'm sending a notification to the iOS device.
2- When the notification arrives, I click on it immediately and it opens the app.
3- The app is open but I can see again the toast with the notification.

But, with the #2 if I'm waiting 3-4s before to click on the notification, the app is opening but I can't see again the notification.

It's like there is 2 concurrents thread : if I click on the notification it's starting a new thread with the app opening but the thread "notification received" is not finish and this is why I can see the notification again... It's a supposition...
What do you think about ?

Thank you

Start by reproducing the two notification timing cases described in the issue: opening immediately versus waiting 3–4 seconds. Trace the iOS notification receipt and app-opening flow to determine why the toast appears twice, then verify that the notification is shown only once in both cases.
