I'm a pretty big Apple fan but it's really been an abysmal experience trying to watch F1 on the Apple TV app now that they have the rights in the US.
I too can confirm I am suffering from this poorly handled nightmare of how to find SkySports coverage and learning it has a shelf life for how long it can be accessed after races.
Apple, you already made it as hard as it possibly could have been to even find the SkySports steams of the events with the coverage that anyone who has followed the sport in the US knows and loves and now without warning SkySports broadcast replays now disappear from past events so anyone catching up after who knows how many days because you won't tell us - Apple - the only option is to watch coverage from the Apple TV commentary team.
Really frustrating experience from what has historically been the leader of best-in-class user experiences for anyone and wants coverage continuity of Crofty and co. from past seasons to this season now that Apple has the contract...
To make sure its specifically stated, as a US viewer for the past 5+ years of F1 coverate I was able to watch any race, qual, sprint and sprint qual with SkySports commentary for up to 9-12 months after the event aired without having to jump through even half the hoops I've had to do with Apple so far this season from past service providers.......
Even the search trick mentioned in other comments is not working for me unfortunately...
