I'm not glad you have this issue, but I'm glad you opened a post about this issue.
I previously hijacked a post (Call History) complaining how Contour has become sluggish while responding to inputs from my remote control.
Of course, the standard reply from Cox was it's my fault: I've allowed my cables to loosen; I've failed to replace my set-top box; I've failed to schedule a technician. Why is bad service always my fault?
I first noticed the sluggishness in September. After rebooting and refreshing to no resolve, I attributed the sluggishness to a then-recent software update (v103.1.0). I had another update on 7 Oct (v104.1.0) but the box is still sluggish.
This is an issue with Cox. Cox either can't fix a bug in their software or something is causing latency on their CATV system (noise, congestion, bottlenecking, mismanagement).
This could be a regional glitch. I'm in Northern Virginia.
