Native spooter and radio subtitles

Since the game's release to this day, only a few people have questioned this, even though you have the options in the game's settings, it's not functional. For these people, the popular Crew Chief APP is recommended, but I would still like this to be effectively native to the game, since there are such options in the settings. Until a few updates ago, the subtitles (Radio Subtitles) were functional and then they stopped working too.
I'm sure my point won't speed up the process of making this fully functional, but it did spark a thread of hope to see that at least on one track it works: “Jacarepaguá Oval”.
