Hello @Huhenyo ,
Welcome to our community.
Look likes that after updating parental control time limits in the Tether app, the app continues to display the old/previous time limit values — even immediately after saving — while the router's web interface correctly reflects the changes.
Here are some troubleshooting steps that you can try:
• Force close and reopen the Tether app after making changes to see if the updated values load correctly.
• Log out of the Tether app and log back in, which can sometimes force a full data refresh from the router.
• Check for any available updates for the Tether app in your device's app store, as a newer version may have addressed this abnormal display.
If the problem persists after trying these steps, we recommend sending an email to forumsupport.usa@tp-link.com with the following information:
