Reposting as the original question is marked solved so not getting traction on my reply-- is there a timeline for adding the ability within Jira Work Management to nest three levels of the hierarchy within the list view (as described here)? Chase originally indicated this would be coming this September, and am hoping to get an update on the timeline before we spend too much effort on the workaround.
Essentially what we're looking for is the ability to create an Epic > Task > Sub-task (or Epic > Story > Task) hierarchy that nests together within the list view. Currently there is only the ability to nest two levels (e.g. Epic > Sub-task).
I ran into the same problem and I found out that the Customer Portal is not able to show any attachments added to the ticket through the JIRA interface.
The way I solved this problem was by uploading the attachments through the Customer Portal, instead of the JIRA User Interface.
Now, if you have attachments already added to the JIRA ticket and you want to expose them to the client, you can add a public comment ("Respond to customer"), and add the following markup tag to display the attachment.
[^atachment_name]
Don't forget the "^" symbol!
This should display the attachment as part of the comment and make it available to your customers.
