iPhone isn't syncing with desktop and vice versa

I got the Brave browser today, and when I imported my google data to the brave browser, everything worked correctly. But when I downloaded Brave on my iPhone, and tried syncing them, they didn’t sync. They are both in the same sync chain, so that worked correctly. And I have every sync setting on. But they just won’t sync, and I can’t figure out how to fix it. Anyone have any solutions?

Brave Version: 1.24.86

Types of devices in sync chain: Windows 10, iOS
