I joined the #Nostr group on #SimpleX I have three groups named Nostrishes nite. Is that normal?
Did you join only using that one link given above? If yes, then it shouldn’t be normal.. That's the link of only one group. And once you are connected, you can not connect again from the same SimpleX account. So I really can't understand how you have three groups.
