I want to cancel one of the two licenses.

I don't currently use one license.

I don't want to pay additional money for unused programs.

Do you mean you have two different plans? With separate bills? Contact Adobe. There may be an early cancellation penalty. Warning: Adobe will not contact you, but scammers might.

Hi,

Can you please elaborate on which plan you have bought (Individual or teams plan), products (Creative Cloud, document cloud), etc.?

Have a look at the Cancel subscription document for more details. Let me know if I could help.

Thank you
