I didn't set up any filters. I even disabled the spam filter. I see some posts from these relays, but not all. A lot of posts disappear from the feed, but I can see all those posts if I go to the author's page. And it's definitely not a tagging issue. So far, I can say that wisp and 0xchat show all posts from both public and private contacts. I hope this will be fixed in Amethyst, because right now Amethyst seems almost perfect as a Nostr app in terms of functionality. Once, I somehow managed to fix this, but after restarting it stopped working again (maybe the cache wasn't saved).
