I used to be able to create a Crucible review from the Commits page but no longer.
In the Development panel, click Commits link and on the page was a tab where you could create a review for all commits or an individual commit but that tab is no longer appearing.
When I create the review in Crucible by browsing change sets with commit comments containing the Jira id it links the review to the jira but no link to the review appears in the Development tab in the jira.
I am using Atlassian hosted Jira Service Desk Application 3.3.0-OD and on premises FishEye and Crucible 3.9.1.
