Scope
Why do the subscriptions keep loading while I scroll down on the subscription index page?
I can't find the list of pages on the Customer index page.
Summary
On the earlier version of Leap UI, the list of items on index pages such as Customers, Subscriptions, Plans, Addons, Charges, Transactions, and Invoice pages will have paginated up to 20 items per page and you need to navigate to a number of pages to view all the items. With the new UI enhancements on Leap UI, you will have all the items on a single page.
Solution
Vertical Scroll Bar on Index Pages
You can now scroll the index pages - Customers, Subscriptions, Invoices, and Credit Notes vertically. Earlier, the pages will be paginated with 20 items per page which may prolong your search however with the new enhancement as you scroll down the list it will load all other data in a single page as highlighted below on the screenshot.
