I am a bit confused about the Prorated options for Upgrading a Subscription Plan. I have this scenario:
Plan A costs £100 and is being retired.
Plan B costs £65 and will be the new plan that people will upgrade to.
Which option should I set for Prorated so that the member's renewal date remains the same but the next payment price is lower at £65.
So, a Member signs up on the 1st of the month, they then upgrade on the 20th month but no payment is taken again until the 1st of the next month, at which time it will process the lower payment amount.
