I don't know how to play jungle anymore

I used to be a jungler main, for years i almost solely played the role, but since pre-season i somewhat took a break from the role. I either didn't play at all, or played support.

Now it feels like i can't play jungler anymore, it feels like my playstyle doesn't fit the meta anymore. Jungle exp and gold were nerfed multiple times, plating were introduced. It feels like i can't evaluate fights anymore, i feel squishier, i deal less damage. With good map awareness i would punish laners for over-extending, counter-jungle when the enemy jungler is away, secure objectives, etc. But it feels like that's not enough anymore.

What changed so much since pre-season 9 that it feels like i don't know how to play jungler anymore??
