Custom text channels not working?

Title says it all. I am adding a player to a custom text channel, but when they speak, it’s registering under RBXGeneral?

-- Server
print(1)
TextChatService.CustomChannels["Artist"]:AddUserAsync(self.Artist.UserId)

-- Client
TextChatService.OnIncomingMessage = function(message: TextChatMessage)
		local TextChatMessageProperties = Instance.new("TextChatMessageProperties")
        print(message.TextChannel, message.TextSource)
		if TextChatService.TextChannels:FindFirstChild(message.TextChannel.Name) then
			return
		end

		if message.TextSource then
			print("Do fun stuff")
		end

		return TextChatMessageProperties
	end
