@fghaz02 Do not “uninstall brave and delete all its user data” or you will lose any earnings and/or balances in your unverified Rewards. Just submit the form and follow that process. Just be patient. You’ve waited this long, just wait a little longer to get your account unflagged by a method that will retain whatever you currently have accumulated.
However, you should backup your Brave-Browser and/or User Data folders just in case your OS or Brave crashes for some unexpected reason. You may be able to restore your Rewards earnings and balances from the backup. Posting the information below.

Note: Consider backing up entire Brave-Browser folder too and not just User Data folder.
Take care.
