A. Check the app settings to ensure that SMS tracking is enabled. Navigate to the settings menu, look for 'SMS Tracking' or 'Text Message Monitoring', and toggle it on if it is off. If the option is not available, consult the user manual for any specific requirements or limitations regarding SMS tracking.

B. If SMS tracking is not functioning as expected, try uninstalling and reinstalling the app. This can sometimes resolve issues related to permissions or settings that may have been incorrectly configured during the initial installation.
