I've tried this a few times late last year and it didn't work, and I tried again just now and it still didn't work. I ran the 'Refresh number of finds' about 5 minutes ago, after logging 20 finds today. The job ran, and is 'ready', as shown in the bar on the top right. But the number of finds PGC shows me as having hasn't changed to take account of the 20 that I've logged.
