I have Jira and Confluence cloud, which have their application links automatically configured by SYSTEM. When I use the /jira macro in Confluence to add/create issues, I get HTTP errors 500 and 504. Most every tutorial I see online says this is an OAuth issue with the application link, but since the link was created by Atlassian, I have no way of changing those settings.
I have not been able to get this feature to work for as long as I have had the product.
