How do I disable rounded corners and minimal toolbar in Edge Dev?

[LGDMps]

Edge://flags/ settings of "Microsoft Edge rounded corners" and "Microsoft Edge minimal toolbar experience" in Edge Dev are COMPLETELY NOT WORKING currently. I have disabled both of them and restarted Edge but they are still here. How can I disable rounded corners and minimal toolbar in Edge Dev?

I'm seeing the same thing. If we're going to have to live with rounded corners on the browser viewing area and there's no way to turn it off, I'm going to switch to Opera until this gets fixed in Edge because it's just makes me want to shut off the browser that badly.

These flags seem to be broken in the latest version. Been reported in another thread.

You can use the Canary build. These changes haven't hit that yet.

It's a known issue and Microsoft are working on it.
