I'm at Challenge 6 and I'm stuck. I've tested that my code produces the Chatter post to the group, and my AnnouncementQueueable class implements Queuable. I've implemented the excecute() method. But still I get this error:

"Challenge Not yet complete... here's what's wrong: 
Ensure that you implement the Queueable interface in the announcementsQueueable class."

Anyone have an answer? I'd love to complete my PDII before end of year. This feels like a testing defect.
