Hi @laekipia,
Welcome to the Auth0 Community!
I understand you’ve encountered issues with the login page on both iOS and Android simulators display a blank page even though it works fine on actual devices.
I have encountered this issue happening recently and the suggested fix is to update everything to the latest version for the React Native, Auth0 React Native SDK, and iOS 18.4 or newer.
For more details on this, I recommend checking out this related thread.
Let me know how this goes for you.
Best regards,
Rueben
