Adobe XD for Jira Cloud app configuration not saving
I am trying to use the Adobe XD app for Jira (https://helpx.adobe.com/xd/user-guide.html/xd/help/jira-add-on.ug.html).
I like the idea of this app because having a dedicated field in my Jira tickets to paste an XD link allows my team to have a dedicated place to look for design work. It also has nice unfurls which is better than just pasting in a plain text URL.
However, I seem to be stuck on step 5 of the attached link. I have gotten the app installed in Jira, but whenever I configure the app it will not save my configuration (the step with the screenshot shown in the link above). That means that I cannot enable the app for any of my projects, so nothing about it is working.
Is this a known issue? Is the app outdated? Any help on how I can make the configuration stick would be great.
