AARP Paramount Plus 10% discount not working

All,

Did Paramount Plus drop the AARP 10% discount?  I tried using the link but it pops up as 404 not found then just defaults to the regular website. When I try signing up and using AARP as the promo code it says it's not valid. I know the AARP code worked last week on Tuesday because I help my neighbor sign up and it worked. I've never had Paramount so I was setting up a new account.

Thanks,

Fred
