Yellow Premove Squares Gone?

During live games, I used to be able to click a piece and it would highlight in yellow.  Then, when I was ready to move, I could click to the new square and the piece would move there.

Recently, this yellow square disappeared.  Click to move still works, but half of the time it doesn't work, and I have to click the piece and then the move a second time.  This adds a lot of time to the clock.

Anyone know why this changed, or how to switch it back?  I have premoves and click to move enabled.

*NOTE: I'm talking about on the website, not the app.

@AunTheKnight, what browser or system are you using?  I tried both chrome and firefox on a mac

Ah. I think there have been problems with Mac before. Google Chrome and Safari work fine for me.
