Yo guys, just had the problem with the Storage permission where the app on my phone when open wants the permission but in the system it does not want it and so you cant give it any permission. Just found out some sick Unreal Engine Project settings that have to be set up in order to be able to set all the permissions you want (the phone will ask you for them when you open the app and you can agree or not). So here is an Image. Hope it helps someone
