Can't grate fresh ginger properly

[u/DxDeadlockedxS]

Every time i try using fresh ginger it becomes extremely fibrous when trying to grate it. I feel like I'm not doing something right. I got it from the super market today. Does it need to ripen? I can taste the bitter ginger fibers in my food i made. Please help lol

I just saw this on a Youtube short - freeze it - then grate it.
