I have been enjoying the racing archive of F1 TV, but the UI is in serious need of an overhaul. It looks sleek at first sight, but navigating it is not great. That is in the browser. Why? Because the iPad app is actually worse. On the computer, you can right-click on races and open them in a new tab, which helps a little. But still, both the app and web service are in dire need of an overhaul.
Once that is covered, they REALLY need to create an app for smart TV's, meaning AppleTV/Roku/Chromecast/FireTV and whatever else is out there. It is great that we now have a streaming subscription service, but mirroring it from another device onto your TV isn't good enough.
Also, they currently have nothing before 1981, but it is said they are working on expanding the archive.
They really should have a feedback form on their site or in their app. There is no way to make suggestions or file complaints.
