(De-)Archiving issues. Troubleshooting didn't work

Yeah, that’s frustrating. Unfortunately, once a chat is deleted, there isn’t currently a way to restore it. One thing that helps is periodically cleaning up older/unneeded chats instead of keeping a very large history, since accidental deletions can be hard to recover from later. I’ll also flag this feedback internally since a few people have run into the same issue and better recovery options would definitely help here. - Avinash
