Taking over the baton for @Frida, @502LSH. While I've not come across this promotion on my Square Terminal before, I'm wondering if you could tap on the three lines to get to the Menu > Notifications. From there, you might be able to see this promotion appear as an "unread" notification, and once you tap on it, it should disappear. Please let us know how you go!
