@adxymmmf1noytb0 like mentioned by @SAGE84 (thanks! 
), the latest version is 0.63.55. And yours is a bit outdated.
Are you on Windows? Can you try:
- download the installer again from brave.com/download or if you have a copy on your machine
- then run the installer. No need to uninstall. Just run the installer. It’ll fetch the latest version.
Additionally, you can find info about the latest version in this forum. Like Hotfix for Release Channel [v0.63.48 --> v0.63.55] released!
Or @brave on Twitter also tweet about the latest release.
