I don't know why I'm still having problems with Nostr, and I think it is not client related, because I tried lots of them BUT, I still have some problems with speed (clients just block or wait for something), posting (clients tell me it could not send a note but in reallity it has so usually I end up with multiple same notes), some notes are seen on some clients or within one account, but not within other (using same relays) etc....
