I'll reiterate what @chaddy@feddit.de says. Sports streams are so finicky and the F1TV app is full of tons of content that doesn't seem to make it to the high seas. I understand pirated streams for pay-per-view events, or sports (like soccer) that are dispersed across a million different broadcasters, but F1TV has so much content.

If you are in the USA, F1TV is a ridiculously good deal here, if it's in your budget. If you are elsewhere, it's worth VPNing for (that's kinda pirate-y, right?) Especially if you split with friends, as I believe you can stream three screens simultaneously. And if you do find some streams, F1TV is $3/mo for full access to everything, including replays, just without the live race stream.
