Hi @BulboBill, thanks for bringing this to our attention.
While Brave isn't officially supported, it is based on Chrome so it does work normally as I use Brave on my personal machine, and the Dropbox site loads without any issues.
Could you clarify what you're seeing on your account? Is the site not loading at all or has grey bars, or are there literally no files on the account?
This will help me to assist further!
