Add 'linked issues' (like blockers) to tickets

[Justin Mann]

If you clone a ticket, it automatically creates a link. So the functionality seems to be available? How do I create a 'linked issue' to another ticket, like if ticket A blocks ticket B?

I only see that message when I move one of the Statuses that has tickets in that status, out of the column back to the unmapped staatus column.

I have not build any quick filters yet. If it was a quick filter, there is a message that says 'issues may be hidden by a quick filter'

The message I see when I open the board is 'no issues are currently vissable'

This is the only project/board where I have had this problem

Do you see the message some issues/task are not displayed due to filter? Also check the if any quick filter is slected or not.
