@Nadine211 if your internet connection is of the older partial fibre type you can hit issues as watching in UHD on a Glass TV requires around 25Mb/s bandwidth the same applies to your Stream puck so unless your connection is faster than 50Mb/s you will hit issues. .Given the speed of your connection depends on the length of your phone line and is essentially therfore fixed the easiest work round is to agree to watch in HD quality when wanting to view at the same time as that drops the bandwidth to 10Mb/s for each unit.
As and when connections are upgraded to full fibre then bandwidth usually disapears.
