ApplyOnNextBillingCycle not working as expected

[firstsale]

I am testing BillingReplacementBehavior and had expected to be able to control when downgrades take place or at least to be control how the downgrade / cancellation is prorated. 

I had wanted to use an entry level usage based plan and then let users upgrade to month subscriptions with a usage limit bundled into the subscription. After testing, downgrading from the monthly plan to the usage based plan happen immediately and I am not able to control how the prorating work.  I really wanted to avoid creating more complex hybrid subscription + usage plans, but I think this may be the only way to achieve the pricing structure I was after. 

Anyone find a way to accomplish this or similar?

If you are using test mode for the billing API, unfortunately it does not reflect the real behaviour when downgrading.

Thanks! I searched around for previous threads on this. Not sure how I missed that one. 

Billing seems like one of the more important areas of the API to have complete and consistent test coverage of between test and prod...
