Not sure that I understand. HBO Now is $15 a month. Are you saying you were paying for HBO Now and also had it free from Verizon? HBO Go is the app you use if you subscribe through a Cable Provider. Fox example you would use your Verizon login
credentials to access HBO Go. If you already have an account with HBO Now that won't have no bearing on your FiOS service.
HBO Now is designed mainly for cord cutters who have no other way to get HBO.
So either subscribe to HBO via FIOS and then have access to HBO GO App or HBO Now.
