Requests sent to the app while it is \"waking up\" may fail due to a timeout. As a result, some events may never be successfully delivered. So some events/requests to the affected app may be lost silently when the app is in cold start and takes too long to respond.\n\n## Simulation\n\nThis is an intermittent behavior, so it is not possible to simulate.\n\n## Workaround\n\nIn some situations, you can reprocess the scenario, since the app is already \"awake\" at that point."}
