Hey, this is a known issue. The review controls moved into the breadcrumb/tab area at the top of the editor after the layout update.
We already added a setting to choose where they show up: Settings > Layout > Review Control Location. You can pick Breadcrumb, at the bottom next to the code, or Island, at the top right. This setting is available in Nightly right now, and it’ll come to Stable in one of the next releases.
If you want to try it now, you can switch to the Nightly release track.
