I apologize for the frustration and service issue. There is a known issue with the Spectrum App on Roku platforms. Our engineers are aware of the issue and working to restore services as quickly as possible. Unfortunately, there is not an ETA.

I just lost my local channels today on my ROKU stick and my smart TV. I tried reinstalling the Spectrum App and reset modem/router to no avail.
HERE'S WHAT WORKED.
I went to my account profile under "Spectrum TV App" and simply saved the channel list. Didn't block anything just saved it. I then restarted the App on both my ROKU and Smart TV and all the channels were there.
Hope this helps others/Spectrum to debug the issue.
I do apologize for the issues. There was a known issue with the Roku not showing channels under 100 . Logging out of the app and back in. may resolve the issue. If that does not work uninstall and reinstall the app. If that still does not fix it please let us know.

Problem has been corrected. Although I've done this many times over the past 2 months, did it again last night. Removed the Spectrum app, and had added it back again to the roku. It worked on all 3 rokus, so I suspect that a new app version is available.
So, long story short and awhile with the tech on the phone, got this problem fixed. The tech "reauthorized" my modem. Then I unplugged the power to that same modem and my router for a few minutes. Repowered everything back, and this is what solved the problem. Now the Spectrum tv app works on all my devices (android phone and tablet, Roku stick, Roku 4 Ultra, and Roku 1 on my home network. I got to keep my own modem and router.
Sad that not everybody has experienced the same seamless upgrade I did. I seem to remember that the S500 error indicates something wrong on the TWC side, but I've only had that error once, and it appeared to resove itself (probably due to a bunch of people in some TWC building somewhere working frantically away).
My only thoughts on things like blurry screens are the usual troubleshooting:
If you've done all that and it still doesn't work, it's time to contact support directly. Anecdotally, my cable card stopped working recently and it was only after contacting support that they discovered my account had been split into two cities, meaning my equipment was receiving conflicting information. Odd things happen, and sometimes somebody just has to dig for the cause of the problem.
