Add metadata to my in-app purchase ios

in my case it was approved after adding the following description to the end of the description:

Subscription:

• Title: Upgrade to premium

• Length of subscription: 1 year (length of the subscription)

• Price of subscription: price / Year

• Payment will be charged to iTunes Account at confirmation of purchase

• Account will be charged for renewal within 24-hours prior to the end of the current period, and identify the cost of the renewal

• Subscriptions may be managed by the user and auto-renewal may be turned off by going to the user's Account Settings after purchase

• Any unused portion of a free trial period, if offered, will be forfeited when the user purchases a subscription to that publication, where applicable

Many thanks to @Paulw11! My app was approved. The clue was to insert all metadata text into the app description like:

---
Features:
....

Subscription:
[ price / length / title / 
  Account will be charged for 
  renewal within 24-hours 
  prior to the end ... etc ]
