I know this has been asked and answered several times, but I have tried all the solutions and I'm still having this problem.
This is my board filter:
project = VP3 AND issuetype in (standardIssueTypes(), subTaskIssueTypes()) ORDER BY Rank ASC
Should include Subtasks, right?
I have enabled swimlanes based on stories, and the subtasks use the same workflow as the other issues, so the status/column mappings should be fine, but I am still seeing 0 subtasks on the board. 
What am I missing here?
