What you've described is my experience exactly, right down to the timing. I tried working through the problem with the folks at TCL, but have not been able to remedy the situation. I believe, as has been suggested to me by others, that the fault lies with Spectrum. Based on what others have told me about their dealings with Spectrum Tech Support, I've been procrastinating going down that particular rabbit hole, but that time is coming. I was told by some that Spectrum tried to blame the matter on the other components like Roku and TCL, but when it was resolved it was because it was addressed as a Spectrum issue. I don't know the specifics of the remedy. It makes sense that if the TV works for every other app that Roku is delivering (or carrying?) that the stink is on Spectrum. BTW, the freezing occurs with both wired and wireless connections and the wireless is tested to be coming in at approx. 220MbPS and TCL displays that as "Excellent". I will update if I resolve the matter.
