Analysis board can't be flipped

Before Lichess v2 I had no problems with the site, but after the new update I'm unable to flip the analysis board - clicking on the three bars at the bottom of the screen has no effect. I'm running FireFox v60

This still remains a problem, has anyone else experienced this?

Can you flip it by typing "f"?

@fuxia yes, thanks so much! Did not know that was a feature.
