It actually happened before 1.8.112. The HF isn't involved in that. It could be because of the May payout, but the reports started to come before 1.8.112.

As being affected by the problem, it would be very helpful if there was a step by step guide on how to export the database and especially how to get the database from the device and where to send it.

Settings->Developer options->Rewards Debug->Export Rewards Database

The database should appear in Downloads folder under the Rewards folder.

Note: If you are not seeing Developer Options, then to make Developer Options visible, you need to have tapped on the Application version preference 7 times over your lifetime.

You can send it to the Brave staff who is working with you.

1. Please do not delete or reset your device in attempts to solve this issue. This will reset your browser data, BAT balance, and will likely result in BAT loss.

2. As of v1.10 of Android, users can verify their Brave Rewards wallet with Uphold. If you are affected by this issue/bug, you can still go ahead and verify your Brave Rewards wallet if you so choose. However, if you would rather play it safe and not undertake any major operations to your wallet while affected by this bug, that is OK too. Verifying is not necessary!
