Hi Nur,
When you publish your app, it uses the database associated with the deployed environment (e.g., test, acceptance, or production), which is different from your local environment. Ensure that the user account you’re using to log in exists in the published environment’s database.
Hi
Ensure that the user data (username, password) in your development database is the same as in your production database. If you’re using a cloud service or separate environments, ensure that your production environment is properly synced.
Hi Nur,
Go to your App security -> Double click on it -> Go to Demo Users -> Copy the admin username & password then login by that credentials.
After that make your own new users on publish environment.
Hope you like the answer
