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 or the component level.

Dedicated egress IPs route egress (outbound) traffic from an app. To route ingress (inbound) traffic to an app, use one of App Platform’s public ingress IPs.
Add the root domain to the list of domains in the app’s settings along with the wildcard subdomain.
App Platform apps may be slow or unable to resolve .gov domains because the domain administrators have blocked DigitalOcean’s IP addresses. To fix this, you can contact the domain administrator or use a custom DNS resolver.
