How can I disconnect a device from a partner exchange?
In Brave click the triangle BAT icon in the address bar, or navigate to
brave://rewards, then click "Wallet verified", then "Disconnect from Brave Rewards".
Be aware that this only stops your BAT from being sent to the partner exchange - unfortunately at the moment this does not stop the exchange from counting the device towards your 4 device limit.
The Brave team are working on a way to allow users to properly disconnect devices from partner exchanges. We don't have an ETA for when it will be done, but if you have reached the limit and need to free up a single slot you can request the support team to manually do it by following the steps here: https://community.brave.com/t/how-to-submit-a-wallet-unlinking-request/294537 [Current November 16 2021]
