In most cases this works really well. It's distracting enough to make sure you don't just ignore it and wipe out your prod data. It is also really configurable but still easy to use. Unfortunately I'm getting an error in a React App we've written. And possibly it's messing with the html before react has had a chance to create it. (Mentioned here: https://react.dev/errors/418?invariant=418 ) . Perhaps, a little delay before creating fix this? It attaches the banner correctly if I tend on the extension after React has finished loading.
