I’ve been playing for almost 2 months. I’m a senior lord 1. I have a bunch of different knights parades tickets but I’m never able to join any of them. Whenever I click on it, it only gives me the option to view rankings. Not to enter any of them. I remember weeks ago I was able to enter a couple when I finally unlocked the feature. But I’m not able to anymore. Anyone know why that is? How do I enter them?
