I've had a quiz accepted in the category required but it is still telling me that I haven't met that challenge yet so I cant move on.

Not sure if this belongs here or on Author board so will post on both

Did you create the template after getting the TRIC category assigned? You cannot use a template that had already been started for TRIC challenges.

And did you stay in the X challenge (obviously not on that screen, but without moving away from it back to another part of the challenge to explore your options) while you wrote and submitted it? If you move away before it goes online, the point won't get awarded. Once the quiz is online, you go to the X Challenge page, then move to claim your reward. If you leave too early, it doesn't work.

I started the template and submitted it after I got the assigned category. I didn't move anywhere until today when I went back to see what my next challenge was. I thought it awarded me an X but then took me back to the same challenge again and says I haven't completed it
