Unity IAP free trial for iOS

Hey guys,

How to I correctly setup a 7 free trial for an iOS subscription using Unity IAP?

When I set it up in App Store Connect nothing really happens. Do I need to setup anything extra in Unity or xCode for it to work?

Do I need to make an app update to make Introductory Offers available?

@tobias_unity Please describe what happens. Are you able to make the purchase?
