No longer getting notified

I’m no longer getting notifications when people start trades with me! I don’t check the trade tab unless it has a notification that a trade was started and, even when I do, new trades don’t appear until the person starting it has ended it! I’ve missed out on three or four important trades because of this! Why is this happening?
