I am developing an iOS app in React Native. I have been testing my application on two iPhones - iPhone 6 running iOS 12.4 and iPhone 11 Pro Max running the latest - 13.2.2.
I am having the strange problem that my application restarts when it is minimized in background and not used on the latest iOS. However, my app would continue from where it has been left after long periods of time on iOS 12.4 - in short it will not restart when in background, which is exactly what I want.
I wish to keep my app on the last state the user left it when navigating away from it, so the user can go back and continue their process. How can I fix this? How come an older iPhone with older hardware and older software manages to keep my application running in the background while the newest flagship with its latest software cannot manage it?
P.S. I had the same issue on one of the previous versions of iOS 13. I was really happy when I read that 13.2.2has addressed this issue and I was hoping it would fix my problem. Unfortunately, it did not.
I would appreciate any ways and guides of debugging this problem and fixing it.
