It is because ‘Moldova is not supported by BRAVE for verification of rewards’. You will be able to use Uphold till Uphold is supported in your region (Nothing to do with Brave). This is essentially a step taken by Brave, backed by Uphold & Gemini. You will still be earning BATs, only you won’t be able to withdraw them out of the Brave Browser. Once region is restored you should be able to re - connect.
