I have a Google mini and a smart TV in my home. I need to stop my children from casting to these. Does anyone know how I do this?
According to the Chromecast design it possible for everybody within the same WiFi network to cast, check THIS link.
If your children have a supervised account they are not able to cast if they have a certain age. Check THIS link.
Thank you so much for your reply 😊 unfortunately I need to prevent my kids from casting as they are casting their own stuff at inappropriate times and arguments ensue.
