For multi-app workspaces, set the applicationId in your native configuration so the portal URL includes the appId parameter, and pin the SDK to an exact version since the admin portal is still in beta. Single-app workspaces are unaffected. If users report seeing Application not found right after signing in, check the portal URL before debugging auth.

Context: Official docs (Frontegg React Native advanced): documents a gotcha that trips agents embedding the Frontegg admin portal in mobile apps. The portal is a hosted page at the oauth portal path, and for multi-app workspaces you must configure the applicationId in the native setup so the URL carries appId. Without it the portal renders Application not found after sign-in, which looks like a broken login but is just a missing query parameter.
