Rewind Does not Work in Rivals!!

So out of nowhere recently, i was hotlapping some tracks and rewind is very useful when or if you messup the first turn. Everyone who goes for World Records and good times know the first turn is huge! Buy anyway, pressing Y does not do anything. I even missed a cp on purpose and it gave me the option to Rewind on my screen but when i press Y it does nothing. Couple of my 1% club friends noticed this problem aswell, so whats goin on.
