There’s been a delay with being able to reference existing attachments in the issue view. This feature is still a top priority for us and we will continue work on this project as a top priority. For now you can still temporarily click through to the old view to reference attachments in the old view.

Work on attachment referencing in the new issue view has begun! When this feature is released, you’ll be able to reference existing attachments in comments and fields using the editor. This ticket is a top priority we’re currently working on and will be done after we transition everyone to the new issue view.
Make sure to watch this issue for updates on our progress.
