Heartbeat and data sending do not work if the app is in the background

I'm extremely confused. How is this related to Traccar? How is it related to this topic?

I asked one thing about the upload—why it had been modified. You answered that, and we started discussing the topic. That’s all. But feel free to delete the comments.

I thought we're discussing the topic, but you keep making some statements completely unrelated to Traccar or the topic.
