You have to add the RSS relay, and then you have to get the website link and then add the Noster RSS address after that url, and then from what I'm reading you're just supposed to go to the profile and add it. But when I go to those RSS profiles on Amethyst, it shows a bunch of posts and then they all disappear really really fast so I'm not really understanding the point here. RSS doesn't work in other Noster apps either I just don't understand. There's a few RSS profiles that work like one for stacker news I'm trying to make some for Reddit but I don't know why they're not working.
