A. 1. Check Google Play Store: Open the Google Play Store, search for ProgressBook Parent/Student, and see if an 'Update' button is available. If not, the app may already be up to date. 2. Clear Play Store cache: Go to Settings > Apps > Google Play Store > Storage > Clear Cache. This can help resolve issues with the Play Store not showing updates. 3. Restart your device: Sometimes, a simple restart can refresh the Play Store and show available updates.

B. 4. Uninstall and reinstall: If you cannot find an update option, uninstall the app and then reinstall it from the Google Play Store to ensure you have the latest version.
