Since sync (v2) is currently not a feature on ios :
Please take down iOS sync misinformation here
Well, that’s an old post. 
And the fact that Sync v2 also coming to iOS. Currently in Beta testing.
It was the top result when I googled brave sync ios. I’m not saying it wasn’t accurate when it was posted. Glad to hear it should be accurate again soon. But currently, it’s misinformation.
