Inverted screen

I pressed a button to try an inverted screen where the elements from the right side to the left. Now I don’t find the way back. Any ideas?

I suspect you accidentally opted in to the right to left test. go to any observation page, scroll to the bottom, and you should see a banner asking if you want to opt out

Thanks. I pressed the button to see what would happen. I was too blind to see the opt out button.
