It's expected that Brave-iOS has fewer fingerprinting protections than brave-core given platform limitations on iOS, but Safari-iOS should be worse. I'm not sure how to interpret the following:
So Brave-iOS has worse protection than Safari but better than Brave-Mac.
Are you comparing Brave-iOS against Safari-iOS? Also, Brave-iOS will not have better protection than Brave-Mac.
Description
On iOS, the Brave browser has something broken in regards to the fingerprint blocking. I've been testing on https://coveryourtracks.eff.org on both my iPhone and Mac. All tests conducted in private windows. I have tested with the "Test with a real tracking company" option on and off. On iOS, fingerprint valid, presumably traceable hashes were listed on the page, and it said i'm only partially protected. Contrast this with Brave on Mac showing everything is randomized(ideal).

Steps to reproduce
Actual result
Short Description
The Mac results show Brave has a randomized fingerprint. The Brave iOS results show actual values for the hashes which show as randomized in the Mac results, and it gives me a rating of "Partial protection."
FWIW, I ran the same test in Safari with "advanced tracking & fingerprint protection" on in a private tab, and it also gave me "Partial protection" but unlike Brave-iOS, it just states the fingerprint hashes are randomized, like Brave-Mac. So Brave-iOS has worse protection than Safari but better than Brave-Mac.
In addition to the summarized results below, I will attach full renders of the results web page from both devices, which has the full technical breakdown.

Expected result
I expect the iOS version to provide the same level of robust randomization for fingerprint protection as the Mac version.
