I was issued a cloud site for training purposes (ACP-620) and have had trouble accessing it on any browser for a month now. I've tried Chrome, Firefox, and Edge. None of the demo cloud site user credentials seem to be working. I am copying in the usernames and passwords to ensure there are no typos.
When I enter a username at the cloud URL, it redirects to atlassian.university. When I enter the username and password into that login screen, nothing happens. There are no error messages or redirects. I have tried all of the demo accounts that were issued to me and none seem to work.
