If battery optimizations are enabled ([Doze mode](https://developer.android.com/training/monitoring-device-state/doze-standby)),
Android might stop the app, which will result in not sending and receiving messages anymore.
Android will stop the app when it is running in the background, resulting in no more messages being sent and received in the background anymore.
It shouldn't be necessary to disable battery optimizations,
Manufacturers also tweak Android rather often to stop apps in the background for ostensibly better battery life, please [see here](https://dontkillmyapp.com/) for more details.
but unfortunately modifications by manufacturers often [require it anyway](https://dontkillmyapp.com/).
