There seems to have been a rework of https://www.redhat.com/en/interactive-labs to extend it to other products, and AAP got a hit along the way. Right now the page has a teaser of three AAP labs, the first one being "Event-Driven Controller: get up and running". Unfortunately, the link on that card leads to another (archived) lab, "Write your first playbook". If you click "See all" to open all AAP labs and find the same lab there, the link at that card is correct.
