This refers to the "shortcut button" on the top left of the screen, next to the BitBucket logo.
My organisation uses BitBucket, and Confluence(onDemand)/Jira(onDemand).
When clicking that button from BitBucket, the following is displayed:
"Connect Bitbucket with other great Atlassian products"
If I click the same button in Confluence or Jira, all the application links are displayed, and work correctly.
My BitBucket check-in's do appear correctly in Jira, so the systems appear to be linked correctly.
