Their commentary comes from Sky. Doesn't matter where your VPN says you are, it's still Sky commentary in English. Although, there is no build up. So there's only commentary from when - on Sky - you get the F1 theme tune and intro. So, no grid walk etc. I kind of like it, you just get the sounds and shots of the grid.
I paid via Google Pay, In £s, per month. Might cost a bit more overall - but you can never count on how long a service like this will work - plus, if you cancel the winter months - it should work out cheaper.
It's a funny situation, because I'm pretty sure Liberty Media coudln't give a toss about the exclusivity deal Bernie made with Sky - and would much rather we all paid them directly via the F1 app. However they need to be seen to be honouring that deal. I'm sure Sky are moaning constantly to them to prevent UK viewers using their service.
