Question:

 My media player won't go away from my notifications even when I've closed the app. What's going on?

Answer:

 With Android 11, developers have introduced a new media player panel within the notifications section. This feature allows some media player apps to remain visible and resumable even after you've closed them using the Recent Apps menu or similar methods.

This behavior is intentional and designed to provide users with an easier way to resume their media playback without having to reopen the app every time. Some of these apps also include a resume button within their own app menus, making it more convenient for users to pick up where they left off.

However, if you see a media player notification panel remaining active, it will eventually disappear on its own after a certain period of time. This ensures that your device doesn't get cluttered with unnecessary notifications.
