How to change your Aero subscription

To change your Aero subscription, navigate to Account Settings > Billing & Subscription.

Click the Change Subscription button.
Choose the subscription you want to switch to. If you have too many active users for the subscription you choose, you will not be allowed to change subscriptions until you reduce the number of active users.
After your subscription is updated, you'll be returned to the main Billing and Subscription screen where you can see your current subscription and your billing details.
