CMS Discount Code Won't Apply

Hello all!

I am trying to apply a coupon code for startups, which is very time-sensitive. Every time I try applying the code, I get the following error - “Cannot use Promo Code: Not valid for this type of purchase.”
And the coupon is strictly for CMS trying to get three months off…

I’ve tried reaching support and got no answer…

Anyone have any idea?

Any luck here? I have no response as well.
