I have a Philips 50PFK6550/12 TV, and a Nexus 5X running Marshmallow. When I try to cast the screen of my Nexus to the TV using the Cast button in the notifications menu, the cast app crashes on my TV:
Unfortunately, Chromecast Android Shell has stopped.
I can then report this error. If I view the stack trace, it says:
java.lang.securityException: Cast mirroring is not enabled.
Trying to cast a tab from Google Chrome on my desktop gives the same error.
Is there some way I can make this work, or is this something Google/Philips needs to fix?
