A few questions about subscriptions

  1. Can the user use the Pay Up Front Offer if he already has the subscription? If it’s so, how does it work: as a subscription downgrade or as an upgrade? Can we sell subscriptions with Pay Up Front Offers for a few years?

  2. How does chargeback work? Do we get a notification about it?

  3. Is there a protection mechanism against receiving free trials on one device under different Apple IDs?

  4. If a user has already taken a Trial when he chooses another subscription in the same group, which also has a Trial, will the current Trial be saved?
