I've spent 3 hours this morning trying to get this to work, it should be easy!
I am using this tutorial: https://confluence.atlassian.com/adminjiracloud/connect-jira-cloud-to-bitbucket-cloud-814188428.html
If you're connecting a Jira Software project:
Choose
Settings > Projects.
Select the project you want to connect with.
In the project sidebar, choose Add item.
Enter the Bitbucket repo's URL you want to connect.
Once the link is created, choose Integrate Bitbucket to sync your Jira and Bitbucket accounts.
Once the link is created where does this Integrate Bitbucket option appear! Its not clear any help I look for the menu system has changed in the posts on how to do this.
All I want is to link jira issues to commits!
