Kindly, please check attached files, we implemented same thing in native app. This is our AppDelegate.swift

Thank you for the updates. To keep things brief, could you please review my initial post? It includes the problem statement, steps to reproduce, and details of the exact issue we are facing. If you require any additional information, please let us know. Kindly check and advise if there is any alternative solution for kill mode in iOS. Thank you for your time and support.

Hi, we need this functionality so is there any alternative to fix this issue? Kindly, please let me know.

Thank you for the update. As I understand it, URLSession will not work if the user forcefully terminates the application, and therefore the API call will not be executed. Please let me know if my understanding is incorrect.

Thank you for your updates. How do the custom notification buttons for MS Outlook and MS Teams continue to work even after the applications have been manually force-quit or killed? or What background mechanism allows background notification actions to function after an app (like Outlook/Teams) is forcefully terminated by the user?

Thank you for your response. We have also tried using URLSession and will revalidate from our end. Additionally, we connected with the Microsoft team. They confirmed that .NET MAUI is a wrapper over Apple’s native APIs, and this behavior is governed by iOS limitations. When an app is forcefully terminated, all background network tasks are cancelled and cannot resume unless the app is relaunched. Hence, this behavior is expected and cannot be controlled from the application side.PFA.
