Is the auto-renewable In-App-Purchase price tier set in iTunes Connect per subscription period or per month?
E.g. An IAP with subscription period 3 months and price tier 99ct, does it charge 99ct every month or 99ct for 3 months?
The docs say:
Price Tier: The price tier at which you want to sell the subscription for this duration.
Since there is also a 7 day subscription period I would assume that the price is for the period. On the other hand all other periods are multiples of 1 month.
If you give 3 Month as time period they will charge you every 3 month.
Based on your Example query they charge 99ct for 3 months
