Phantom 4 Pro app crashing

I will start by saying this has not affected my ability to complete flights. A couple things have caught my eye while flying. If a flight goes longer than 15 mins, the app will no longer track the position of the drone. The drone continues to fly its route, I just cannot see where it is, other than line of sight. Also switching between camera view and overall route view will cause the same issue. Mostly any moving or selecting of anything in the app causes it to freeze. The drone continues flying and returns home upon completion, but the app will crash as soon as the drone lands. Just curious if that was common, or if there is something I could do to help this. TIA
