Explanation
The Mobile User permission is required for users to access Salesforce features on their mobile devices, such as the Salesforce app. This permission enables users to log in to the app and sync data between their devices and Salesforce. Therefore, when preparing and conducting testing for Manufacturing Cloud for mobile, it is important to assign the Mobile User permission to the test users, so that they can view and approve sales agreements on their mobile devices.
