I am having the same issue. Can we please get a response from someone who is with tech support at Roku?
This forum is not technical support. While there are Roku moderators, and they do attempt to assist users with issues, that's not the forum's purpose.
While what you said is true, what other options might he have?
Basil, I wish I had something to offer him. I wish that Roku either had an email address for technical support, or made use of this forum for actual customer support. I know Shawn works hard here trying to help people, but Roku needs to offer better technical support. I've tried the app myself, and encounter the same error, so I'm certain it's nothing with the end user. The app itself has a bug, and if Roku is the one responsible for it they need to address it. I just checked in the Apple app store, and it shows Roku Inc as the developer, but no method of support for it. All I can offer right now would be to enter a bad review in the app store and see if that gets their attention. I've also heard that Roku seems to respond to posts on their Facebook page, so that might be another option.
