I'm in a whatsapp group chat that has a fairly large amount of messages, as well as a lot of traffic (people joining and leaving the chat). To help me keep only the messages I actually need I delete all the unneeded messages, but then I get a situation where I have pages on pages filled with administrative messages about people leaving and joining. Is there a way to delete those messages to clear up the chat?
