Hey Sara,
Have you switched on security in the Mendix studio?
Let me know please
Hi Sara,
Rishabh is referring to these settings. If this is enabled, you’ll have to grant your use read+write rights on the entity Review, to be able to read/edit the attributes.
As an app is built in preview mode from studio I’d expect you not to be able to enter any data.
Publish the app and open the app to interact with the form would be the option to test your app and enter some data.(https://docs.mendix.com/studio/publishing-app/)
