More info on coupons
I've been able to find a fault in the coupon system through testing. Running two coupons in PS4 I've logged on as a user and initiated a purchase using a coupon, then logged off and re-logged on as the same user and used the other coupon code in PS4 and it prints the wrong coupon used (the coupon title from the first purchase) on the screen order review invoice.
It's not making a change in the coupon used even when logging off as the user and logging on again. It's like the coupon first used by the user is cached with the user rather than looking up the appropriate coupon code submitted at checkout.
This is a serious problem. The more I work with the coupon system the more I'm loosing confidence that it's actually working correctly and providing me with appropriate feedback that it's obvious what's being used as the coupon code. This really needs to be address and corrected ASAP.
