Hi @Rob2310 and welcome to the forum. In case you are not aware, even though Netflix is included in your monthly subscription you still need to activate it.
Have a look at THIS link to see if it helps you. It covers registering in detail but included Sky Q and well as Glass/Stream so make sure you follow the correct part.
Good luck.
