Hi Martyn Bell,
Response for Cloud Version
RE: 'I cant even get it to show open ones'
-> I'm not sure what you mean. Your screen shot shows the linked Jira issue. If you mean that Linked Assets isn't showing in your JSM Fields, that may be owing to the fact that you need to adjust the screens to show that field in project settings.
If you're still having issues for cloud, please elaborate.
Attached are 2 screen shots showing a ticket with multiple linked assets and one showing the asset detail if you click into it.
You are right. Sometimes Insight just says Error without explaining what the error is. Especially when importing CSV - it is like a field of mines - just a step to the left or right and it blows up.
Also some parts are still not working. E.g. when you export objects with attributes with multiple values it separates them with |. When you import the same file back - it does not import attributes because it needs ||. Even if you set separator to | in settings - it does not work.
