I have the app on an appletv.
It worked well, especially after they enabled a no-spoiler style part way into the 2023 season.
What’s a no spoiler style?
At the beginning of the season, one would open the app, and every thumbnail of every practice/race had the results in each title.
I communicated my dismay through the MotoGP website, and in their answer they said they were aware of the issue, and it would take some time to get the issue fixed.
I think it took to nearly midseason for it to resolve.
