If you downgrade your app plan from one paid plan to another paid plan, or if you downgrade your workload tier while your subscription is active, those changes will take effect immediately. For example, if you downgrade from the Team plan to the Growth plan, you will immediately lose access to the features of the Team plan but will be charged a prorated amount for the unused time on the Team plan on your next billing cycle invoice. (Please note that downgrading your app to the Free plan and then re-upgrading does not result in a prorated charge!)

When it comes to downgrading workload tiers, those changes also take effect immediately and will not wait until your workload units reset before switching your tier. For example, if you downgrade from Tier 3 (2.5 million workload units) to Tier 2 (750k workload units), on the 20th of the month, when you are charged for overages at 12 AM UTC on the last day of the month, it will only take into account the 750k additional workload units from Tier 2. When you downgrade workload tiers, you will be charged a prorated amount for the unused time on the higher tier in your next billing cycle invoice.
