I have not heard any reports of the Disney+ X1 app being offered by any Canadian cable provider that uses Comcast's tech. I have no idea what the reasons are for the delay in getting the app up here either.
FYI, looks like the X1 app may also have been rushed out. It is still under development and a recent update finally allows for watching 4K content on Xi6 set-top boxes.
Is Disney+ in 4K?
4K content is available if you use the Disney+ app on X1 and have an Xi6 TV Box, or on Flex with an Xi6 streaming TV Box (along with a compatible 4K or 4K/HDR TV).
It's a safe bet that getting 4K support working is a higher priority for Comcast than adding support/localization for the Canadian market.
While I can appreciate that having Disney+ (and other streaming apps) all together on the Xi6 tv box together with Ignite TV is very convenient, especially with the all-in-one voice search functionality using the Ignite tv remote, there are other ways to get Disney+
If you have an Xbox One/X/S or a PS4/5, you can get Disney+ on those consoles and its performance is actually quite good. You can also pickup a FireTV stick or a Roku stick fairly cheaply and have all of your streaming apps (+ 10s of 1000s more) together in one place...and those apps tend to work better on those devices in my opinion.
We're another step closer to getting the Disney+ app on Ignite TV!!! 😄 🍿
The "Disney+" voice command now produces an "APPS-04154" error, indicating that the app is failing to load. The system recognizes Disney+ as a valid app. However, the app cannot load because it has not been shipped to our set-top boxes... yet. I also got a suggestion to do a voice search for "WandaVision on Disney+". 😎
This is the best early confirmation that we can get that Rogers is now testing the Disney+ app internally, so it's only a matter of time before they add it to our Apps menu!
