Edit the quantity of addons on "Add One-Time Charges and Addons" page.
Problem Statement
You want to edit the quantity of addons when adding them through the Add One-Time Charges and Addons option.
Solution
You can edit the number of addons while adding through the 'Add One-Time Charges and Addons' option. There is an option to edit the price per unit, and quantity for unit-based addons whereas for flat fee addons, you will be able to edit only the amount and not the quantity.
Once you go to subscription details page -> click on 'Add One-Time Charges and Addons'
Click on Add One-Time Addon, search for your unit-based addon, configure the timeline, and click Add. You will see the page below where you can edit the quantity.
This feature is available in both Leap and Classic UI.
