Same here. I can't cast the Spectrum TV app. The app is on a Roku but not on a Firestick. Its unbeleivable Spectrum does what it does. The money they spend on advertising should be spent on technolgy instead. I'm looking into Sling TV. By the way, I have been a TWC customer for over 15 years, so much for loyality.
Roku is the only supported set top streaming device outside of select Samsung smart tvs and the Xbox One. Roku paid for this exclusivity and until that deal expires there will be no support for Fire TV, Apple TV, Chromecast, or any other streaming device.
Although our Spectrum TV application does not support the Fire Stick there are
some of our partner applications that do. You can see those here:
Spectrum-Social Media Customer Care
Lead Moderator-Community Forums
Each channel App lists what devices they are supported on. AMC is online only.
It is my understanding ( I do not use The Fire Stick or Android devices myself) that
If it says Fire TV it would work with the Fire Stick. There are not many on the list
but there are some.
I can find no means to watch Spectrum on the Amazon Fire TV and I've tried everything I can imagine, and some I can't.
Short of becoming a developer who can decompile the app and take out a check for the HDMI output being in use (which it must be on a FIre TV) don't see it happenig unless Spectrum changes their mind.
Especially since Time Warner Cable customers were already using our Fire TV's for cable TV until I was forced to upgrade to the Spectrum app and then the app tells me it doesn't work on this device. Is Spectrum under no obligation to honor the advertisements of compatibility TWC made prior to the sale?
At this point I would consider buying a Roku but what garuntee do I have Spectrum won't kill that app next week like they killed the Fire TV app? None, apparently.
Roku paid good money to make sure they are the only platform the app is available on this class of device. As a consumer, we have no visibility as to the terms of these agreements so yes, you have no guarantees.
