When one person deletes the link and other doesn't know about it and tries to send message, it shows failed to send message try again. This doesn't give a clear message to the user that link is deleted. It can also convey that there might be other issue like network problem or such.
If I am opening the same link from the tab that I have deleted, it says waiting for alice to join whereas other person is already joined.
