I have exactly the same problem. I can activate any channel on my ROKU except IDGO. its infuriating and I can the same error if I try to activate from my IPhone or computer and also regardless of whether I use Safari, Edge or Chrome.. Has anyone figured out a solution?
It’s DirectTV. We previously had it working fine in the Roku but were prompted to reavtivate after a few months and norms get this problem.
If we Trey to register to watch on our computer it’s fine - it just had this problem activating on the computer to watch the Roku ID app
