You can use this to reset 1 device for Uphold, however, it will take quite some time for them to process. You will have to wait until they email you back. Unable to re-verify wallet - #118 by Mattches
Each install of brave counts as a device limit. So even tho you do not have active accounts connected, it still counts as a device towards the limit, this includes all reformats you may have done where you re downloaded brave and connected it to Uphold etc.
