I can't find a way of doing nor find any info on how to stop devices casting to my TV from the button youtube has put on their videos. The kids keep doing it and it is very annoying.
I know I can go into each of their devices and turn casting off / stop them searching for local devices but surely the TV owner should be able to setup access permissions on the TV.
I went into the youtube app and unlinked them all but as soon as they go on youtube and click on that darned button they aren't asked for a pin or anything. They just click on my TV and it re-links them.
Any ideas? There really should be a way within the TV of deciding who/what can cast to it.
