OnMessageReceived event missed raising sometime

[Engineerumair]

I have written an application where i attached event handler to SlackSocketClient OnMessageReceived and it works well and receives messages.

I also tested with sending messages from one member to another it works great.

I have subscribed to channel #article_notifications (https://www.theinformation.com/) and I also receive messages when some message is received on the channel but sometimes it doesn't raise the event and it misses to receive the message.
