Hi everyone. I finished my file and sent it, but the grader did not accept it. He said there were several mistakes, but I tested the file and saw that it worked. I also changed my file a few times because the grader did not accept it, but nothing changed. I want to know where I made mistakes.

1. Laptop switching — on my end, it works correctly.
2. Hold button — when you press it, it mutes all microphones and sends the lobby music to the far end. It works on my file.
3. UCI gain control — this is the part I really do not understand. Because I already configured it so that when the fader goes to the bottom, it mutes automatically. But the grader still did not accept it.
4. Q-LAN — the grader said that the music is not going to pass through Q-LAN, but that does not make sense to me. Because it is a simple setup, and you only need to select the transmitter name on the second core.

Maybe I did my file complex and grader just want me to simplify this. But it does not mean it is not work. Can someone have any idea what I have to do? Thanks.
