In Jira 8.17 and later, the link to comment, delete, and edit buttons are no longer available. Although there are workarounds to perform these actions, its a bit counterintuitive, especially the link to comment feature which requires you to extract the link via the comment time stamp.
Is it possible to add these buttons back in future JIRA releases or provide a more intuitive way to perform these actions.
