I couldn't find the option ethier until I scrolled up in settings/content manager/drive, it was hidden for me and was driving me nuts because I remembered the option, it should be the first one.
BTW This happened to me on Mugello, and I already tried everything that everyone has recommended in addition to verifying game cache and even deleting the track and re downloading it through the verification, nothing worked.
I'm running the latest Sol update but on preview 49 of shaders patch because some of the latest were giving me trouble.
