Is it possible to fully integrate Jira v8.8 with Confluence Cloud? I've successfuly linked Jira and Confluence through Application links and status is Connected but I have problems with further actions, for example I can't add Confluence pages to Epics because Jira can't find any linked pages (I've created few of them) as if Jira can't get through to Confluence. Same issue appeared when I tried to insert Jira issue to Confluence page - Confluence can't find issues from Jira (there's a lot of them).
If full integration is possible, what can I do to make it work?
