Deleting neighbours' Android tv

[Zey]

I don't know how, but I'm connected to my neighbour's android TV and also I don't even know who they are. I always have a notification about what they are watching and I don't want to know it. I tried to delete the device but I couldn't. Please help me.

That will happen if you are both on the same WiFi network.   Is that the situation?

The only way to stop that it to be on different networks.
