I generated a userid and password, then tried to access mycompany.atlassian.net (for JIRA demo)
I first saw a login screen, I entered userid and pw, it then redirected me to a page asking the same things plus typing in a displayed alphanumeric string. Tried this many times, reset the password to make sure, still a problem. I was able to log into this site withi the same userid and pw.
It's been a day now and no closer to a simple demo of the software. The "help" is absolutely atrocious, should be able to resolve something like this in a hurry (or perhaps it's a bug).
