ReportBuilder is an excellent tool for distributing sophisticated reports you just can't replicate in Catalyst, but it's limited to allow a maximum of 10 scheduled reports per account.
That's just too few. I also had to use two slots because the system would not let me both FTP and email the same report on the same schedule. The FTP works but the email never arrives.
Please explain the status change to "already offered"
I was told that each seat gets only 10 reports.
