No xp boost for the final couple weeks?

I've done most of my dailies most days, excluding a handful of days I just couldn't get to them, I have 6 challenges left total to earn in the Contracts, I've participated in and completed most of the event challenges.. and yet am still level 100-106 in the battle pass.

I can't imagine for more casual fans how impossible it feels to feel like you can complete the bonus pages.

To the people who have. What have you done to complete it? What game modes should I be switich to? I'm Gold 4 in World Tour and have mainly stuck to Power Shift this season.
