Hi @Dood68_0, Since you already have Brave installed and it only appeared when checking for updates, this usually means your current Android version no longer meets the minimum requirement for newer releases.
The Play Store listing now requires Android 10 or higher. The Samsung Galaxy S8 Note SM-N950F appears to have officially stopped at Android 9.
Could you please confirm:
• Your current Android version, found under Settings > About phone
• The current Brave version installed on your device
If you are on Android 9, that would explain why the Play Store says it is not supported. In that case, the installed version may continue working for now, but it would no longer receive updates.
