Recorte Para Windows 7

Is the ISP GPON Router/Modem Wi-Fi capable? If it also has wireless function, try to enable the Wi-Fi on it, then connect the android note 9 to that network to check if you can use those apps. If not, is more like an issue on the android note 9 phone itself, you can try to uninsall those apps, clear the cache, and reinstall them, check again if you can use them.
