Just FYI, if you were thinking Brave Sync is identically to Firefox’s. Apart from iOS sync still remaining crippled, Brave’s Windows and Android Sync does not work for all types of History sync, unlike Firefox’s.
Specifically, only URLs that are typed into the address bar are synced. If you clicked on a hyperlink in Brave, not synced. If you opened a link from Mail app in Brave, not synced.
At this point, the official answer from Brave is: Typed URLs only. No word if they intend to improve the situation.
I described the problem a little more in detail in the link below.
