thank you for reply。 I am sure not using content-available:1 in payload with push notifications。 also our App offers NFC functionality, but it has very few users. from the log，users terminate the app and then didFinishLaunchingWithOptions was called immediately。 I think something was doing in the App, but we have not find them。 the runtime logs from the real user, and i can not reproduce it，and i will log LaunchOptions to find if if has something usefully. The phenomenon is that after the app is terminated, a cold start is immediately triggered in the background. if have more informations， thank you for sharing it.
