I had a bit of trouble getting these up and running. I put these in before any users joined:
However, they didn’t work. Eventually I discovered it (wondering why my test email was so quiet). Deleted all the tags and re-entered them, but didn’t fix them.
I made it work in the end, but had to delete the tags, put in different tags, delete them, put the original tags back and then they gave me the dialogue (apply to all users, etc) and worked.
