Is there a way to refund everyone when cancelling a performance, rather than having the Ticketing staff go through each order?
There is the Event Cancellation Utility that should help with this!
I've never used this utility. I'm playing with it in Test - is there anything I should know before I do this Live?
Do you use TMS and Adyen?
Depending on how you are refunding (check, credit card, on account) you may need to run the utility a few times. I believe it also only operates on the performance level (so you can't cancel a prod season en masse). I think Jessica is alluding to it, but there are considerations if you're refunding to a bunch of credit cards - talking to your bank will help with any issues.
