skatup I just made Brave my default browser until GOS fixes this, what I call a problem.
Sorry to disappoint, but GOS likely won't solve fingerprinting, and Brave doesn't solve it either.
The EFF test isn't considered the best these days, you might want to try something like CreepJS, which will show you almost no browser can actually resist fingerprinting (only the TOR browser and Mullvad Browser on desktop can resist fingerprinting in any meaningful way IMO).
At some point I built a custom sandbox for Brave with Bubblewrap on Linux, which randomized various values (timezone, locale, fonts and a bunch of other stuff) on each run, and yet CreepJS could still semi-reliably assign me the same fingerprint (and this setup was barely usable anyway).
