I have a Windows 10 PC, a Rewards wallet that had been in use for several months, and I am a Brave Verified Creator. I recently had to reinstall Windows, but I had the foresight to make sure that I had saved the Wallet passphrase to LastPass so that I could restore my balance with the Import button.
(alas, I forgot about my bookmarks, but that’s a different sob story)
When I reinstalled Brave and plugged in my passphrase, I only had the previous month’s payout in my Wallet. 100BAT of savings were gone.
It’s unclear to me whether the passphrase I saved was actually just my “Verified Creator” balance, or whether the passphrase is only intended to support the previous month of transactions, but I sure wish I’d known I would lose those BAT when I was looking at the export screen!
