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.
I feel your frustration. By the way, what does Pure Digital have to do with this? I believe it is beyond Roku's problem too. It's the channel itself.
I DID contact them. (Classic Reel) They are fixing the problem, but it is taking a long time. If you look at previous posts you will see the explanation. But to sum it up, COVID-19 and stay-at-home requirements has increased the number of subscribers to where the servers cannot handle the load. The movies are being transferred to a new server. Newly added movies are already on the new server. It looks like those in the Film Noir category are also okay because I watched many of them without interruption.
Check with your internet provider to see if there is a different, lesser used “route” which will give you the speed to support movies. Been years since I’ve done that, thinking it’s a change in you IP address. You may have to call back to talk to a different service rep who knows what to do. Years back, had to change to a less busy route every once in a while. Saved us from having to change to a more expensive plan to get the speed we should have been getting in the first place. The more people using the same route, the slower your internet.
