unable to purchase premium subscription

harry.inc.us

I am trying to purchase subscription but it says "You cannot purchase this product with your account

We're sorry, the product you are attempting to purchase is not compatible with your LastPass account. Please logout and use a different account, or contact support for help." can anyone help on this ?

LastPass Support

@harry.inc.us​ I'm sorry for the error there.

It appears you previously subscribed through a mobile app store, which has its own billing / subscription system. I've removed that restriction so you may purchase directly through lastpass.com.
