Recently got a new marshmallow box at work running 6.0.1 Marshmallow Ninja and im trying to load in BBC iplayer via sideload to see if we can get it working. Im currently using the Nvidia shield version as a source as its the only version besides FireTV that has the Leanback UI build in. In an attempt to get it to work i have decompiled the APK in order to see how its functioning. Leanback is already loaded into this, but the app keeps redirecting me to the Iplayer webpage instead of using the Leanback UI that the shield outputs.

Has anyone encountered this before/Knows a workaround/knows why its doing it? Any help would be appreciated :)
