You guys don't have enough information on this problem? Have you ever looked through the threads associated with HBOMax on Roku? This has been going on since October. "we" as a collective, have posted the make and model of Roku devices, SN, IP Protocols, Version of OS for Roku's and Ap versions of the HBOMax application. We have followed the Standard.. uninstall, restart, unplug, reinstall, turn on turn off guidelines. How about the people at ROKU get with the people at HBO Max and figure out why we are getting the error codes... and if the error codes that are coming up don't tell you what the problem is, then develop some codes that will...I have given up on using the HBOMax application and am just using AirPlay...I even went so far as to install a brand new Roku Ultra box just to see if my older model was the issue...nope, now HBOMax tries to load, but then just goes back to Roku Home screen...don't even get an error code .. there should be enough information from multiple sources on both the Roku Community Site and the HBOMax support emails for someone to figure out what the problem is.
