How do I access the Pega Academy challenges?

I have tried accessing multiple challenges from the Pega System Architect mission (System Architect | Pega Academy) on both Pega 8.7 Personal Edition and through my Pega Platform (probably 8.7) trial, and it says the login info is invalid in both. For example, I tried logging into the “Manipulating application data” challenge on both editions using username “author@gogoroad” and password “pega123!”, and I got the error: “The information you entered was not recognized”.

Am I using the wrong edition (or version) of Pega to access these challenges? Thanks!

@AnthonyP1627 Hi Anthony, you must use the cloud-based Pega instances available on each challenge page.
