I see on purplepag.es kinds 10050 and 0 for this user. I don't see kind 10002. Without 10002 as a starting point, gossip doesn't know where to go looking for kinds 10050 or kind 0.
I sent a message to fiatjaf and it showed up on Gossip, but Gossip didn't pick the metadata of this key I just created nostr:npub1jnatjw0ac4mf6aeadq8g422pmvfv0hqv7yervlqaj5upjank0npqc4xnpl (although the metadata is on purplepag.es and that is configured as "discovery" for me on Gossip) and Gossip also said it was using NIP-04 but I thought Coop was just NIP-17? nostr:npub1acg6thl5psv62405rljzkj8spesceyfz2c32udakc2ak0dmvfeyse9p35c
In any case neither the initial message nor my response showed up on Coop.
