@sonaliku AEM uses auto-save features that might be capturing changes as soon as they are made, which could explain why the "modified by" field is updated. However, if navigating away from the page without explicitly saving reverts the changes, it indicates that the auto-save might not be fully committing the changes to the repository.Please check the auto-save settings in your AEM instance to ensure that they are configured to commit changes appropriately. You might need to adjust the frequency and conditions under which auto-saves occur
Sharing a document which details the auto-save functionality and session management in AEM, which explains how changes might be captured but not fully committed if sessions are not handled correctly.
