# Why are my App Platform environment variables not updating?

If your app is successfully deploying but your environment variables are remaining unchanged, you may have defined the same variable name at both the app and component levels. Component-level variables override app-level variables.

To fix this, ensure that your variable is defined at the appropriate level: at the [app level](https://docs.digitalocean.com/products/app-platform/how-to/use-environment-variables/index.html.md#define-app-level-environment-variables) or the [component level](https://docs.digitalocean.com/products/app-platform/how-to/use-environment-variables/index.html.md#define-runtime-variables-after-app-creation).
