I have set up some Auto renewable subscription with - 1 month at $10 and - 2 months at $15.
I would like to change it to have 2 months at $5. Should the user upgrade their subscription from 1 month to 2 months, will it still apply even though the cost $5 will be lower than the 1 month at $10.
Refering to the Upgrade description from here: https://help.apple.com/itunes-connect/developer/#/dev7f2d6b652
Will the user still get refunded pro-rata and immediately charged the new lower price?
