When does an update to subscription pricing take place? On the very next payment or does it skip?

I recently updated pricing for some subscriptions just a day or two ahead of the renewal for said subscriptions. But none of the updated pricing was used. All subscriptions seemed to be the old pricing.

Subscriptions screen shows the updated pricing, but Transactions screen shows the old pricing charged to customers.

Is there a set time between updated pricing to actual implementation of new pricing?

Just realized there is a ten day period before the change will take effect. If you're going to update pricing on subscriptions... do it more than ten days out from autocharge dates!
