Install HBOMAX on Roku 3, when you get HBOMAX as a promotion from At&t.
I have HBO Max on my phone which is LG and Chromecast which is hooked up to the TV in one room. In another I have a Roku 3. I received HBOMAX through a promotion from At&t. I have the app on Roku installed but I can't watch anything because Roku 3 wants me to subscribe with a pin number. Can you help?
