Uninstall the previous version and then install the new version to ensure the app starts correctly.

Perform a fresh installation on a device with the latest OS and verify the new storage format works.

Test the new version on a device with an older OS version to check backward compatibility.

Which of the following is a typical compatibility testing scenario for a mobile app?

Testing the app on a device with a different screen resolution

A children's educational app must comply with COPPA, which restricts the collection of personal information from children under 13. The app currently allows users to create profiles with a name and avatar. The team needs to verify that the app does not collect more data than necessary and that parental consent is obtained. Which testing approach is most effective?

Test the app's functionality to ensure that children can create profiles and use the app without errors.

Perform a data flow analysis to trace what personal information is collected, transmitted, and stored, and verify that parental consent is requested before any data collection.

Test the app on a device with parental controls enabled to see if it is blocked.

Review the app's privacy policy to ensure it mentions COPPA compliance.
