We have a number of scheduled report builder sheets that run on a Sunday afternoon so the data is ready for our business teams on a Monday morning.
This weekend they were all delayed, and then cancelled, with a message emailed to us about there being an internal error.
We've been trying to reschedule or run them manually yesterday and today and it has been really slow (sometimes taking 45 minutes to return 100 rows of data).
To the Adobe staff on here: Is there a known problem with report builder? We've got a lot of business users waiting on data and we can't give them an ETA at the moment.
