How do I find and use the new PowerUps for AARP Rewards participants in Word Wipe?

[AARPTeri]

AARP Rewards participants can not only earn Rewards points for playing Word Wipe, but they can score big with two new PowerUps. These PowerUps can double your score in any one round or give you extra time on the game clock to beat a level or even revive your game if the clock expires.

To access, be sure you are logged into your account when playing Word Wipe. If you’re new to AARP Rewards, you must first create or activate your account, but this is fast, easy and free. Then click the “Redeem Rewards PowerUps” tab on the gameboard and the PowerUps panel will open. (The clock pauses while the panel is open so you won’t lose any game time while you select a PowerUp.)  You can open or close the panel and select PowerUps at any time during your game, as long as you only use each only once. Give it a try!

When trying to use the power up in Word Wipe, it gives me an error "Something went wrong".  Also, is it new that the time begins to shorten as you get a higher score?
