According to the official docs for version 1_3: https://developer.apple.com/help/app-store-connect/reference/subscriber-report
I was expecting data being filled in as I also can see it via S2S notifications or in the Subscription Event report for the following fields:
- Subscription Offer Name
- Promotional Offer ID
The field "Subscription Offer Name" is only rarely filled and I have never seen field "Promotional Offer ID" being filled at all, although data shows up in the Subscription Event report.
This causes a serious issue in that we see lower prices for a subscription without any reason.
How do you work around this issue?
