Maybe you need to add more relays. For public relays that have a bit of spam filter (lesser spam than other free public relay), we can use nostr.mom (have more strict spam filter than nos.lol ) and nos.lol . We can also add paid relays like eden.nostr.land and nostr.wine as read-only relays. We can still read the events but not publishing event on those relays if we are not their member.

I can still see notes from Japanese and Chinese usually during Asia Day Time 😅
