This usually occurs when the app you use is updating, which is an enabled setting as default on Android TV, combined with an unstable or slow Internet connection. We suggest you use the BenQ User Dashboard to verify the Internet speed on your Android TV, and to improve the signal strength if it is necessary by switching your network to 5GHz from 2.4GHz, moving your wireless router to a better position, or switching to a Wi-Fi channel that is less congested for better signal strength and internet speed.
