The new updade don't work with Google subscribers

Why google subscribers can't use the new update ? 

I wanted to try the new profile customization but I have an interface like a standard profile and when I click on "unclock with nitro", a error message appears and say than it's not compatible with google subscribtions. I don't understand why you decided that. But please change that because I can't buy a nitro with credit card. I use google because there is paysafecard.

Thank you for reading :)
