ISSUE: Cannot Verify with Uphold: Infinite Spinner/Processing Error
Possible Workaround (from Related Brave GitHub issue report #21057 ):
Disabling ads and reenabling fixes it but may remove the custodian linkage.
I think you can just close the rewards page and reopen another one and enable it. I don’t think a browser restart is required.
