What is the issue or error you’re encountering

I’ve deployed some code in the past via the dashboard and I can’t seem to access it. I’ve rolled back to the version that contains the code but when I use the code editor it still shows the code of the latest release instead of the active release. How can I get the code of an older release?

This specific code is not versioned controlled and I assumed I could always access it via the dashboard but it looks like the editor always picks the latest release instead of the current active release and there doesn’t seem to be a way to switch the editor to a different release.
