Coupon code not working on Pro upgrade

[Uttara Paingankar]

I am trying to use the coupon code shared on the podcast a couple of days ago to upgrade to the Pro account. Based on what was said on the podcast after applying the coupon code, the yearly membership would be $312 if paid yearly (not monthly). But it seems like the coupon code is not even applicable to the yearly membership. I am getting the error 'Sorry, this coupon is only available for Pro Monthly and Plus Monthly subscriptions.'
