yes i agreed, Several people reporting similar issues, i also included.
I think it just doesn't work very well.
just to follow up …
The actions Approve/Deny did appear after the following 2 items:
1) I waited for the Cron to run (actually ran the /admin/cron.php script)
2) I added a 'category' and 'purpose' to the "Data Registry" (previous to this, I had only added same to the "User" branch
Hope this helps someone in future - thanks!
