Our scenario is as follows:
1. A ticket in a particular project and with a particular request type gets opened.
2. An automation creates some subtasks.
3. In the process of an agent executing one of the subtasks, a screenshot is added to the subtask by the agent.
In this scenario, the internal agents can see the screenshot fine. However:
1. In the email that goes to the Reporter, they get "preview unavailable" for the image.
2. If the Reporter goes to the Portal, they see "preview unavailable" there as well.
I understand people have been running into this sort of thing for a while, but most of the discussion was around Confluence, but this is happening in Jira Service Management for us.
