Hello there,
I am trying to link a Confluence (Cloud) Space to my new Jira (Cloud) project.
I already established a bilateral application link between the two services. On both sides it says "connected". Then I added the Jira application link to the application link list of the Confluence space. No problems there.
But when I try to "Connect the project to a confluence space" from the Pages menu of my next-gen Jira project, my space doesn't show up. Linking a Confluence page inside a Jira issue doesn't work either, since no pages can be found.
Please help 
Cheers!
