If you ever suspect your notes aren't broadcasting, Amethyst gives an indicator you can check for. If you pull up the note in question, right under your profile image on the top left side you'll see little images representing every relay your note has broadcast to. You should see all your outbox relays depicted, and some of your general relays as well. If you don't see any, hit the 3 dots on the top right of the note to bring up the menu and select Broadcast. Your note will be re-broadcast and shortly after you should see those little relay indicators appear below your avatar.
