Posts rarely show up for me on Primal. I also can't reply to any of the posts I do see. While I can react with a ❤️ (and it turns out that it was updated since I last used it, and users can react with a ⚡ now, too), the reaction doesn't appear on any other clients, and then it disappears in Primal sometime later. I experienced these problems on Android as well as on my laptop. The one thing that worked well for me in Primal was its search function. I had absolutely no problems with that. So for a while I used Primal only for searching for users, while I used Amethyst for everything else. But then Amethyst got better at its search function (not perfect, but good enough), so I deleted Primal entirely. But now I'm trying out Wisp, and I'm very impressed with it!
