For users who have visual impairments, VoiceOver will read content on the screen and also provide a highly visible focus indicator which may be useful if you have limited vision. There are also features to adjust the colour and contrast of the screen and high contrast keyboards available. Presently the screen size of the app cannot be zoomed with standard gestures although there is a magnifier window within the accessibility settings that works with the app and text size can also be increased.

Streaming requires an internet connection that's free of bottlenecks. However, the internet isn't a direct pipeline from the source to you. Streamed content passes through many other computers on its way to your PC via your ISP. If any one of them is carrying too much other traffic, the streamed content may be interrupted and pause. Our streamed content is 'buffered' to help prevent such problems, but sometimes delays are unavoidable. Usually the delay only lasts a few seconds, and the stream picks up where it stopped. Streaming problems are more likely to occur on a slow computer or device that has a smaller memory and processing power. Even with a fast computer or device, if you have too many applications open it could slow down your media streaming. If you notice things are sluggish, close all unnecessary applications and windows on your computer or device. The faster your network connection (modem, cable, DSL) and computer speed (in megahertz), the higher the quality of the stream.
