You can submit a wallet unlinking request. See “How to Submit a Wallet Unlinking Request” below. I’ve also posted other related information. Linking limits were supposed to be removed after the May payouts but, since some users are still having issues receiving payouts, implementation will probably be delayed again. The Brave GitHub issue report is posted below for reference or if you want to check on status.
