Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
Have had the same problem. I can get HBO MAX on my phone and Kindle but tried to login the HBOMAX app I was able to download to my Roku 3 and Premiere+. There us no option for cable provider log in like Starz has and HBO GO had. After each failed code was given another website to try. Tried each one with a different code and none were recognized. This is a work around that should not have to contend with. They need a direct link to cable options that I have not found. After first login try I noticed it was HBO NOW at the top of the screen not HBO GO that I had previously.
Anyone know an easier way to get access with cable provider info would be greatly appreciated.
You will have to ask HBO about that. There should be some way to authenticate the channel, but only the developer of the channel can assist with that. HBO is the developer of that channel.
