Following was written for HBO on a PC but essentially applies to Starz as well.
A bunch of things lead to problems loging into HBO GO and many other Online Channel sites.
- You must get HBO (or whatever channel you are trying to use) from Verizon
- At least the first time you may first have to sign out of the Verizon site. It gets confused easily.
- You must allow third party cookies
- You must be running Flash, Flash must be allowed to store info for third parties. (not sure what is used instead of FLASH on some other platforms)
- You must not have your Browser options set to delete Information when exiting Browser. Flash takes this as deleting information when exiting a site.
The general way it works is for you to go to HBO GO site. Ask to look at something and it switches in a FRAME pointing to VERIZON and you signin. Verizon stores some information in flash and returns. That information must still be there so that HBO accepts you as authorized.
