Oddbean new post about login | logout I'll leave it for a while and see what happens, I've sent you a small 21 sat zap, after adding the damus relay and got no response, I've just added the primal relay to the list as well, so I'll check again in a bit.
I've seen the same, sometimes it works, sometimes it doesn't, even between two zaps to the same person. Sometimes a zap receipt shows up on nostter, but not on Amethyst. But I guess a lot of relays puke on my follow list 😆
