I completed Jira Admin Parts 1 & 2 last year, and completed the Getting More from Jira Workflows course this past May. However, none of these courses are showing as complete on my Atlassian University profile anymore, and I have lost access to the course materials that I was able to retain after their expiry.
I was going to spend this year completing the optional courses before then attempting a certification but I am unsure if this means my progress has been reset or if it will mean I am unable to get certified without re-doing these courses.
