I opened the link on my phone and saw that there was a room code. I finally figured out that I had to open up a second screen so I went to my computer and I typed in that room code and it said that no phones were available to join, but my phone was sitting there in that same room. I tried creating the room first on my computer then joining that same room as typed on my phone and that also didn't work.
After some time, I realized I needed to take an actual photo of the QR code that was on the website from my phone and only then was I able to actually get into the racer.
Already having spent more time than I would've wanted to I was happy to see the Formula One race on the screen! I accelerated and promptly drove off the track as I apparently cannot steer. Nothing I can do to figure out how to steer.
If this worked, it would've been really neat
