On 11 May, I needed to schedule a redelivery of a product to all those who had purchased it. That is to 162 people, not all that many really. I got it started the normal way. 2 days later, it was still showing as "Scheduled", and finally the next day, that changed to "In Progress", which is where it is still sitting now, as of the time of this writing. It seems to me that 10 days and counting to redeliver to 162 people is a bit slow.

The product in question is https://marketplace.secondlife.com/p/SL-Maps/26193111
