As it is, the browser back button produces some pretty serious issues with the platform. Outsystems pages can rely heavily on their preparations, and preparations don't run with the back button which can lead to outdated displays.
This could lead to a variety of issues, from wasted time using misleading data, all the way to potentially exposing sensitive data through the back stack.
There are ways to force-refresh pages using javascript, but as a low-code platform we aim to minimize the amount of custom javascript in a solution.
The addition of built-in handling to force (or choose to force) pages to refresh with the back button would be a very desirable change.
