We always try to keep Digital Factory and other Ultimaker products bug free, but sometimes something slips through. Apologies for the inconvenience at this time, and we'll restore the functionality as quickly as possible.
To get a clear picture, is the recent history gone from the printer's details page (/app/jobs/{printer-id}) or the new print jobs overview page (/app/print-jobs/history)? Your jobs should show up in both of course if everything works as planned. I personally cannot reproduce, so maybe you can also send me your printer's logs so we can correlate some data.
