I am looking everywhere within MyBT and can't see how to actually add SSME anywhere. Why is this? What kind of terrible UX is this?
Welcome to the Community.
Please click on this link
If you scroll down the page you will see a red button that says Login to add extras this will start the order process.
You can choose to stay on your current subscription and the option to add Sky Sports Main Event will be offered to you.
Let me know if this helps.
I do not see the option for Sky Sports on that page. It has loads and loads of packages but no Sky Sports anywhere.
Add extras to your TV package
Customise your BT TV with Netflix, BT Kids, Sky Cinema and more. .... Log in to add extras
if you click on that Log in to add extras ... you will reach an order page where if you opt to continue on your current subscription and Continue you will proceed to the next page which I believe will be titled
TV: Additional viewing options
Enhance your TV package with extra viewing options so you can watch them just when you want
there you will typically see options for AMC , NETFLIX, music , Sky Sports and Sky Cinema
