Hello, I want to ask regarding details about Coupon system in PlayFab, I have read some previous topics but as it's already few years ago there might be some changes so I just want to make sure. Here are the questions:
1. Are the coupons still don't have expiration date?
2. Are the coupons by default one time use only? As we don't need to verify that the already used coupon won't be able to be used again "by other players".
3. Some topics mentioned that you can't add virtual currency directly from coupon, so does putting it inside a bundle works? And does the bundle need to only contain VC or I can't mix it with some in-game items?
