C# ClientWebSocket doen't receive incoming messages until an outbound message is sent

Question

I'm trying to receive messages from a server in real time, ideally using the ClientWebSocket class. I would like to both send and receive messages on their own. Unfortunately, I always first have to send an outgoing message through WebSocket.SendAsync() and only then new messages arrive with WebSocket.ReceiveAsync(). I tried searching and debugging the code but couldn't find anything that would fix this wrong behavior.

I would like to receive the incoming messages independently of me sending anything. Any help is be appreciated.

    public static void WebsocketReceive()
    {
        while (WebSocket.State == WebSocketState.Open)
        {
            byte[] receiveBuffer = new byte[2048];

            int offset = 0;

            while (true)
            {
                try
                {
                    ArraySegment<byte> bytesReceived = new(receiveBuffer, offset, receiveBuffer.Length);

                    WebSocketReceiveResult result = await WebSocket.ReceiveAsync(bytesReceived, source.Token);
                    offset += result.Count;

                    if (result.EndOfMessage) break;
                }
                catch { break; };
            }

            if (offset != 0)
            {
                Console.WriteLine(Encoding.UTF8.GetString(receiveBuffer, 0, offset));
            }
        }
    }

Edit: more code

This is where I initialize the WebSocket and connect to a server. I don't have access to their code.

WebSocket = new ClientWebSocket();
await WebSocket.ConnectAsync(new Uri("wss://example.com"), Source.Token);

After connecting, I run my WebsocketReceive() method to start collecting incoming messages.

I send messages into the WebSocket from a different method, through this code:

await WebSocket.SendAsync(new ArraySegment<byte>(Encoding.UTF8.GetBytes("message to post")), WebSocketMessageType.Text, true, Source.Token);

I should also provide some more details about how the client and server interact. At the start, I send and receive a few responses, which somehow works. I send some messages and receive responses, which are printed into the console.

What isn't working is specifically when the server wants to send me a message on its own. After a few seconds, I should receive incoming events from the server. This is where it stops printing into the console. Whenever I send any message again all of them come back at once - the loop is repeated for all messages in the "queue".
