After this new update of One UI 3.0 or Android 11 in Galaxy M21, there is no media notifications that are being displayed on lock screen. I'm a MX Player user and I had given it all the required permissions either it be notification, battery or memory. Its actually not convenient to open lock screen all the time just to change song. I don't know about whether Google Play Music is having this issue or not. But I like MX Player's interface.
If anyone can help with this, I would greatly appreciate it.
