We upgraded Commerce from version 13.15.0 to 13.18.2 and campaign total order count is not updated anymore.
I tested by creating a campaign and a offer as seen below on version 13.15. Created one order with a product in the campaign and totals orders and redemptions was set to 1. Then we upgraded to 13.18.2 and created another order with the same product. Redemptions was updated to 2 but total orders was not updated to 2 as expected. Anyone else with this problem?
