Hi everyone,
Please see GabeU and BirdDog's posts regarding Video Data Saver. If you turn it off and the buffering stops, this is because the video service (in this case an on-demand provider) is hard set to HD either by the provider or the user. It is worthwhile checking to see if this can be changed from your end, but if not, our recommendation is to download video with the data saver turned off overnight so it does not impact your data usage.
If turning off Video Data Saver does not resolve your issue, please let us know. Keep in mind this is all dependant on your account having monthly plan data remaining.
