[App] "Save state on exit" not working

This issue is about the iOS app

Whenever I close DB48X and launch it again, I start with a blank calculator. "Save state on exit" is enabled, but does not seem to have any effect.

Enabling "Save state when deactivating" seems to fix it, but then I get spammed with "Saving state" messages whenever simply switching between apps.

iOS 17.6.1

This is a problem with the way iOS deactivates applications. I need to find the correct iOS events, i.e. one that only happen just before application exits, but not when the application is simply "likely" to exit (like on deactivation). So far, no luck with the "obvious" ones.
