I have similar experience with nostr:npub1plstrz6dhu8q4fq0e4rjpxe2fxe5x87y2w6xpm70gh9qh5tt66kqkgkx8j . Some notes, even recent ones are not shown, but I can find them on @damus and nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg . All clients are using the same list of relays, so the problem has to be in the way they are querying and processing the feed.
