Incompatible with my devices – Spectrum TV Review

So I Just brought a 4K AndroidTV by PHILIPS for my bedroom and guess what? This Spectrum TV app isn’t even compatible with the television. So I connected my Roku3 to the TV because it already has the spectrum tv app downloaded, and just as I launched the spectrum app Roku gives me a message I’d never seen before “If you delete the spectrum tv app you won’t be able to reinstall it later”.. So my question is, Why is this app incompatible with certain tv’s and streaming devices?
