Spectrum Killed the TWC App on Roku - TWC TV and Apps

Ever since Spectrum took over TWC, the App on Roku has been nothing but unstable. The service is unreliable. It is constantly unavailable, error messages pop-up, have to log in multiple times, have to reboot the Roku or TWC modem or both to restore service. It has been nothing but a HOT MESS. Before Spectrum took over, there was a nice solid run of good service on that TWC app.
What a nightmare this has been. Unfortunately it looks like FIOS may have to visit the household when it become available in our NYC neighborhood. I hope Spectrum can clean up the mess they made. #SpectrumSucks
