@Jbb7 if you have Sky Stream or Sky Glass it is likely tto be due to poor wifi connection to the Sky hub. You can check the speed by running the network test in the Get Help menu in the Netflix app. To watch Sky sports in UHD you need a steady 30Mb/s. Ethernet where practical is sensible or ensure the hub and puck are out in the open but you may need an extender or simikar.
If watching on a Sky Q or Sky HD+ box yourcsatellite dish is likely to need a slightvadjustment.
