My Spectrum app is available thru Apple TV. I can use the same remote in that case, however, I still have to stop Channels app, start Spectrum app (not as user friendly as Channels, then reverse to get back to Channels.
I prefer to use Channels with the Amazon Fire Stick. For some reason, my "On Now" displays differently using the Fire Stick than it does using Channels on the Apple TV.
Here is what my On Now looks like using Fire Stick:

The programs all have a thumbnail of the program that is on, as well as, showing the network. I am a visual person, so this works well for me.
Here is what my On Now looks like on Apple TV:

Instead of thumbnails, a lot of channels only show the network logo or will have the name of the program, but no thumbnail.
I do have the Spectrum DVR. I only use it to watch programs that did not record properly in Channels. It does not have commercial skip and other features that I enjoy using Channels. I personally find that the Spectrum app is not as user friendly as Channels.
I'm pretty much a geek when it comes to technology, so it is not lack of ability that prevents me from using Spectrum through Apple TV. Due to recent events, it looks like I will have to get over that as I will have no choice but to watch some of my recorded programs from the Spectrum DVR.
They say all good things must come to an end, but I am hopeful that the future will bring back these networks into Channels. To be fair, I'm still waiting for Locast to return!
