So if you have the Sky Sports package which now includes Sky F1 then you can still use it on Sky Go.
If you have not got the Sky Sports package but have Sky F1 from another deal with Sky you still can watch F1 on your STB but they have removed the option for you to have access to F1 on Sky Go??
If the above is correct then like you I don't understand why they have done this to their customers and IMHO this is not a very customer friendly thing to do and to me seems very odd after they've just released a new product in Sky Q
