Why can't I buy a single image on a standard license anymore?

Hello,

I am wanting to buy a single image on adobe stock. I have done this before on a standard license costing around $15, I am trying to do this and now it is wanting me to sign up to a monthly subscription which I do not want to do as I do not use 3 assets a month it is very sporadic when I buy stock. I have spoken to an adobe chat person and they are saying I have to buy an extended license, I have never had to do this before and do not want to spend $90 on something that i have previously gotten for $15.

Has something changed?

Thank you
