On Jumble they were working pretty well two weeks ago, now they're empty, I have zero chats. I don't know why. Maybe because Coop has refreshed my encryption key. Maybe NIP-4E is too complicated and we have to simplify it.
Coop used to work pretty well for a while but a little before the NIP-4E transition started it got pretty broken and hasn't recovered yet. I'm waiting for
@npub1zfss...w445 to finish his mobile app and fix it. Still hopeful.
