😠we don’t support edit in Nos but we do support delete. Is it not working for you? If so I would love to figure out why and get it fixed (I work on Nos).
FWIW I don’t see any replies from you other than this one, so maybe they did successfully get deleted for others but not you? There are a few Nostr apps that don’t respect requests to delete content but it doesn’t sound like that’s what you’ve run into.
