I've setup an upgrade path from our cheaper plans to the more expensive ones, but it still charges the full amount for the more expensive plan. Can I configure the upgrades to only charge the upgrade cost?
Also, is it possible to show all three pricing levels to new users, but hide the lower pricing levels from our current subscribers?
For instance, when I sign up I can choose Plan$1, Plan$2 or Plan$3. Then if I choose Plan$2 I would like to hide Plan$1, and only show Plan$3 as an upgrade.
