What's configured where

SMProxy has two independent layers of configuration — don't confuse them. The provider's configuration always owns routing, chains, balancers and DNS rules. App settings only adjust how the client behaves around that configuration.

Layer	Controlled by · documented in
Subscription / routing / branding	The provider, via subscription response headers and the config body — see the developer docs.
App settings	The user, in the app's Settings screen — this page.
