Dear Brave Rewards Users,
If you’ve experienced an issue with BAT not successfully porting from your browser wallet to your Uphold wallet, please upgrade your browser to v1.22.67. Once upgraded, then disconnect and reconnect your Uphold wallet. BAT that was earned before the March Rewards Settlement should then drain directly from your browser wallet to your Uphold wallet.
Thank you for your patience as we’ve worked to implement this fix.
The Brave Rewards team
That sure sounds like any BAT earned before March should port to Uphold after the fix was applied and the wallet reconnected.
