I have an HBO Max subscription on my Roku account which I pay for. But I only have a Roku device on 1 TV, and my subscription is through Roku not my cable provider. When I try to log into my account on either my phone or my other TV, which is strictly through cable, no Roku device, I can't get it to work, because it's not through my cable provider. Is there a way around this? Or should I just cancel HBO Max?
