To my knowledge, and even from reading about it on the BAT FAQ page, separate devices constitute different "wallets", at least until they implement their native wallet, for BAT. However, a couple users have claimed to have their rewards synced across devices? Possible or not?
Aside from that, I have been trying to get Brave to sync bookmarks/history/and let me push links between my phone and computer, but it won't let me. Or rather, it says that I already have, it shows both devices as on the "sync chain" in settings, but when I try to share an open tab from phone to computer, it tells me to set up and enable sync?
