I highly recommend you consider switching from Chrome to Brave. Like Chrome, Brave is based on Chromium, but doesn't have a lot of the nonsense that Google has been doing to its browser.
I've just installed Brave (Version 1.25.68 Chromium:
91.0.4472.77 (Official Build) (64-bit)), and the problem addressed by Premium System FAQ #10 remains (the chrome://flags/ settings mentioned at the link in FAQ #10 don't exist among
brave://flags/ (at least, I couldn't discern work-alike settings)). I did allow Brave to import my settings from Chrome (if that might make a difference).
Could FAQ #10 be updated to add (a link to) instructions for Brave?
