How come when I open Amethyst I see notifications that don't show up in Primal and vice versa?
Discussion
Could be something to do with the way Primal caches relay events.
Pinging the developers nostr:npub16c0nh3dnadzqpm76uctf5hqhe2lny344zsmpm6feee9p5rdxaa9q586nvr (Primal) and nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z (Amethyst) who will probably give you a better answer than I can.
Primal has its own special sauce when it comes to relays so things show up different there sometimes.
You shouldn't expect different clients to show the same notifications and the same feed. Everyone has their own filters on what and how to show things. On top of that, several clients now use different relay lists and the direction is to be even more dynamic in the future.
