When I launch Brave on Windows (Probably the same for Windows & Linux) and have it open for awhile it says in the top right to update Chrome. When I click on it it asks me to install Chrome.
I think this is because Chrome rolled out a major update recently to fix a vulnerability in Chrome. Brave needs to roll out this update ASAP and needs to ensure when these quick security updates roll out by Google it can work with Brave ASAP.
