Cordova app crashes when ios app has been in background for 7-9 hours. When clicking on a push notification

Question

I have a angular app which uses cordova for packing it in a native app. Everything works fine except when I click on a push notification when the app has been in the background for 7-9 hours. When this happens the index.html is displayed and nothing else happens. I tried to wrap the bootstrap on angular and the callback of pushNotificationReceived in a try/catch block which is not executed. Which leads me to believe that the angular is not the problem in that case.

Unfortunately I can only reproduce this error only when i wait for 7-9 hours. I suspect that iOS stops the whole process after a certain period of time, but I can't find further information on that.

I found a ticket that sounds kinda similar here: https://github.com/dpa99c/cordova-plugin-firebasex/issues/803 But I can't seem to reproduce the error the way they can.

If anyone knows this bug/error and knows how to fix it or can point me in the right direction would be much appreciated.

Here is my cordova config :
