WiFi Name Change Not Working

I am trying to change my SSID/WiFi name. When I access the Admin tool to change the name, it states "To edit your Wi-Fi Network Name & Network password, please download the Xfinity xFi app or visit xfinity.com/myxfi." I have made multiple attempts to change the name on the app and myxfi, and it says changes complete. However, the old name still shows on my devices and the admin tool, so the name change is not going through.
